Dought & clear, - Guidelines on takfeer (ruling someone to be a kaafir).

We hope that you can define the guidelines by means of which it is possible to determine whether someone is a kaafir or faasiq, so that I will not fall into the innovations into which many groups have fallen. Which books do you advise me to read? Please note that I am a beginner seeker of knowledge.
Praise be to Allaah.
Firstly:
Determining whether someone is a kaafir or a faasiq (faasiq) is not up to us, rather it is up to Allaah, may He be exalted, and His Messenger(peace and blessings of Allaah be upon him). This is one of the rulings of sharee’ah that is to be referred to the Qur’aan and Sunnah, so we should be very careful and base our judgement on clear proof. No one may be judged to be a kaafir or faasiq except the one whom the Qur’aan and Sunnah indicate is a kaafir or faasiq.
The basic principle is that the one who appears outwardly to be a Muslim of good character is regarded as still being a Muslim of good character, until it is proven that this is no longer the case by means of evidence that is acceptable in sharee’ah. It is not permissible to take lightly the matter of judging someone to be a kaafir or faasiq, because that involves two very serious matters:
1 – It implies fabricating lies against Allaah with regard to this ruling, and fabricating lies against the one who is being judged.
2 – Falling into that which one accused one’s brother of, if he is free from that.
InSaheeh al-Bukhaari(6104) andSaheeh Muslim(60) it is narrated from ‘Abd-Allaah ibn ‘Umar (may Allaah be pleased with him) that the Prophet(peace and blessings of Allaah be upon him) said: “If a man declares his brother to be a kaafir, it will apply to one of them.” According to another report: “Either it is as he said, otherwise it will come back to him.”
Secondly:
Based on this, before ruling that a Muslim is a kaafir or a faasiq, two things must be examined:
1 – The evidence of the Qur’aan or Sunnah that this word or this action implies that a person is a kaafir or a faasiq.
2 – Applying this ruling to a specific person who says or does that thing, such that the conditions of judging a person to be a kaafir or faasiq will be met in his case, and there are no impediments.
Among the most important of these conditions are the following:
1 – That he should be aware of his transgression that renders him a kaafir or faasiq, because Allaah says (interpretation of the meaning):
“And whoever contradicts and opposes the Messenger (Muhammadصلى الله عليه وسلم( after the right path has been shown clearly to him, and follows other than the believers’ way, We shall keep him in the path he has chosen, and burn him in Hell — what an evil destination!”
[al-Nisa’ 4:115]
“And Allaah will never lead a people astray after He has guided them until He makes clear to them as to what they should avoid. Verily, Allaah is the All-Knower of everything”
[al-Tawbah 9:115]
Hence the scholars said that a person who denies obligatory duties should not be judged to be a kaafir if he is new in Islam, until that has been explained to him.
2 – A reason why he cannot be ruled to be a kaafir or faasiq is if he does something that incurs such a judgement involuntarily. This may take several forms such as:
For example, he may be forced to do that, so he does that because he is forced to, not because he accepts that. He is not a kaafir in that case, because Allaah says (interpretation of the meaning):
“Whoever disbelieved in Allaah after his belief, except him who is forced thereto and whose heart is at rest with Faith; but such as open their breasts to disbelief, on them is wrath from Allaah, and theirs will be a great torment”
[al-Nahl 16:106]
Another example is when he is not thinking straight, so he does not know what he is saying because of extreme joy or sorrow or fear and so on. The evidence for that is the report narrated inSaheeh Muslim(2744) from Anas ibn Maalik (may Allaah be pleased with him) who said: The Messenger of Allaah(peace and blessings of Allaah be upon him) said: “Allaah rejoices more over the repentance of His slave when he repents to Him than one of you who was on his mount in the wilderness, then he lost it, and his food and drink are on it, and he despairs of finding it. He goes to a tree and lies down in its shade, having lost hope of finding his mount, and whilst he is like that, there it is standing in front of him, so he takes hold of its reins and says, because of his intense joy, ‘O Allaah, You are my slave and I am your lord,’ making this mistake because of his intense joy.”
3 – Misinterpetation. He may have some confusion and some misinterpretation that he adheres to, thinking that it forms evidence for his beliefs, or he may not be able to understand and comprehend shar’i evidence and proof in the proper way. Therefore, judging someone to be a kaafir is not valid except in the case of one who deliberately goes against the shar’i evidence and who knows that he is wrong.
Allaah says (interpretation of the meaning):
“And there is no sin on you concerning that in which you made a mistake, except in regard to what your hearts deliberately intend. And Allaah is Ever Oft‑Forgiving, Most Merciful”
[al-Ahzaab 33:5]
Ibn Taymiyah (may Allaah have mercy on him) said inMajmoo’ al-Fataawa(23/349):
Imam Ahmad (may Allaah be pleased with him) prayed for mercy for them (i.e., the caliphs who were influenced by the view of the Jahamis who claimed that the Qur’aan was created, and supported it) and prayed for forgiveness for them, because he knew that it was not clear to them that they were disbelieving the Messenger and denying what he had brought, rather they misinterpreted and erred, and followed those who said that to them. End quote.
And he (may Allaah have mercy on him) said inMajmoo’ al-Fataawa(12/180):
With regard to takfeer (judging someone to be a kaafir), the correct view is that a member of the ummah of Muhammad(peace and blessings of Allaah be upon him) who strives to reach the truth concerning a certain issue, but reaches the wrong conclusion, is not to be deemed a kaafir, rather he will be forgiven for his mistake. But the one who understands the message brought by the Messenger, but deliberately goes against the way of the Messenger(peace and blessings of Allaah be upon him) after true guidance has become clear to him, and follows a path other than that of the believers, is a kaafir. The one who follows his whims and desires and fails to seek the truth and speaks without knowledge is a disobedient sinner, and may be a faasiq, but he may have some good deeds that outweigh his bad deeds. End quote.
And he (may Allaah have mercy on him) said: (3/229):
However, and those who sit with me know this about me, I am always one of those who most emphatically forbid describing a specific person as a kaafir, faasiq or sinner, unless it is known that shar’i proof has been established against him, and it has been proven whether he is a kaafir, a faasiq or a sinner. I affirm that Allaah has forgiven this ummah for its mistakes, which includes mistakes in narrative and practical issues. The salaf continued to debate many of these issues but none of them testified that anyone else was a kaafir or a faasiq or a sinner.
He mentioned some examples, then he said:
I also state that what has been narrated from the salaf and the imams, stating that the one who says such and such is a kaafir, is also true, but it is essential to differentiate between general rules and specific cases.
… Takfeer is a kind of warning; even though the words may be a rejection of what the Messenger(peace and blessings of Allaah be upon him) said, the man may be new in Islam, or he may have grown up in a remote region. Such a person cannot be ruled to be a kaafir, no matter what he denies, unless proof has been established against him. The man may not have heard of those texts, or he may have heard them but they were nit proven to him , or he may have some ideas that are contrary to what he heard, that med him to misinterpret the text.
I always remember the hadeeth inal-Saheehayn, which speaks of the man who said: “ ‘When I die, burn me and crush (my bones), then scatter me in the sea, for by Allaah, if Allaah grasps hold of me He will punish me as He has not punished anyone else in the world.’ They did that, and Allaah said: ‘What made you do what you did?’ He said: ‘Fear of You.’ And He forgave him.”
This man doubted the power of Allaah and doubted that He would restore him if his remains were scattered; rather he believed that he would not be resurrected, which is kufr according to the consensus of the Muslims. But he was ignorant and did not know about that; however, he was a believer who feared that Allaah would punish him, so He forgave him because of that.
One who is qualified to engage in ijtihaad and who bases his incorrect notion on some misinterpretation of some text but is sincere in his keenness to follow the Messenger(peace and blessings of Allaah be upon him) is even more deserving of forgiveness than such a person. End quote.
(Based onKhaatimah al-Qawaa’id al-Muthlaby Shaykh Ibn ‘Uthaymeen (may Allaah have mercy on him).)
Because the matter of takfeer is so serious, and mistakes therein are so grave, the seeker of knowledge, especially if he is a beginner, should refrain from indulging in that, and he should focus on acquiring beneficial knowledge that will set his own affairs straight in this world and the Hereafter.
Thirdly:
Before we suggest some books to you, we should advise you to seek knowledge directly from scholars of Ahl al-Sunnah, because that is the easiest and safest way; but that is subject to the condition that the one from whom you learn is trustworthy in terms of his knowledge and religious commitment and following of the Sunnah, and in avoidance of whims and desires and innovations.
Muhammad ibn Sireen (may Allaah have mercy on him) said: This knowledge is the (foundation of) religion, so watch from whom you learn your religion. Narrated by Muslim in the Introduction to hisSaheeh.
If it is not possible where you are to attend lessons given by scholars, then you can make use of their tapes, as it has become easy to obtain them on CDs and websites, praise be to Allaah. You can also benefit from some seekers of knowledge who are keen to acquire shar’i knowledge and follow the Sunnah; hardly any place is without such people, in sha Allaah.
Fourthly:
Books which you should strive to acquire and study include the following:
Tafseer:Tasfeer Ibn Sa’di;Tafseer Ibn Katheer.
Hadeeth:al-Arba’een al-Nawawiyyah(al-Nawawi’s 40), with a commentary thereon;al-Ihtimaam bi Jaami’ al-‘Uloom wa’l-Hukamby Ibn Rajab;Riyaadh al-Saaliheen– you may pay special attention to this blessed book, and you can also learn from the commentary thereon by Shaykh Ibn ‘Uthaymeen (may Allaah have mercy on him).
‘Aqeedah: StudyKitaab al-Tawheedby Shaykh Muhammad ibn ‘Abd al-Wahhaab, with its commentary;al-‘Aqeedah al-Waasitiyyahby Shaykh al-Islam Ibn Taymiyah; some other useful essays on this topic such asTahqeeq Kalimat al-Ikhlaasby Ibn Rajab andal-Tuhfah al-‘Iraaqiyyah fi’l-A’maal al-Qalbiyyahby Ibn Taymiyah.
You can also benefit fromZaad al-Ma’aadby Ibn al-Qayyim (may Allaah have mercy on him) and many of his other books such asal-Waabil al-Sayyibandal-Da’ wa’l-Dawa’.
This is a start. If you study these books, especially if there is someone who can help you to read and understand them, then you can move on to other books, in sha Allaah.
And Allaah knows best.
