A person (man) prays in the mosque, prays qiyam al layl, fasts on Monday, Thursday and the 13, 14,15 of each month. Buthe has no achlaaq with: his wife(there is every day quarrel at home), neighbors, relatives of the wife, friend of his wife, other people. What can you say about such person?.
Praise be to Allaah.
Good morals are one of the greatest purposes which the Prophet (peace and blessings of Allaah be upon him) was sent to promote among people. Allaah sent him to establish the religionof truth and a life of fairness and justice among people, after Allaah looked at the people of this earth and disapproved of them and hated what they werefollowing of shirk, ignorance and bad morals, except for the remnants of the People of the Book.
The Prophet (peace and blessings of Allaah be upon him)expressed this great aim, which was one of the aims of his mission, when he said “I have only been sent …” to give the impression that all beliefs and rulings of Islam are only aimed at achieving that purpose, which is to establish good morals and justice and kindness.
He (peace and blessings of Allaah be upon him) said: “I have only been sent to completegood morals.”
Narrated by Ahmad in al-Musnad(2/318) and classed as hasan byal-Albaani in al-Silsilah al-Saheehah (no. 45).
Undoubtedly one of the greatestproblems that some Muslims are suffering from today is the split between worship and morals, whereby the physical practice of acts of worship – in some people – has become like customs or rituals, in which the outward motions are done without any attention to their effect on the heart and soul, even though the four pillars of Islam – which are the most important acts of worship – are aimed at disciplining the soul and improving morals.
For example, concerning prayer Allaah says (interpretation of themeaning):
“Recite (O Muhammad صلى الله عليه وسلم) what has been revealed to you of the Book (the Qur’aan), and performAs‑Salaah (Iqamat‑as‑Salaah). Verily, As‑Salaah (the prayer) prevents from Al‑Fahshaa’ (i.e. great sins of every kind, unlawful sexual intercourse) and Al‑Munkar (i.e. disbelief, polytheism, and every kind of evil wicked deed) and the remembering (praising) of (you by) Allaah (in front of the angels) is greater indeed [than your remembering (praising) of Allaah in prayers]. And Allaah knows what you do”
[al-‘Ankaboot 29:45]
It was narrated that Abu Hurayrah (may Allaah be pleasedwith him) said: A man said: O Messenger of Allaah, “So and so (a woman) – and he spoke of how much she prayed and fasted and gave charity – but she annoys her neighbours withher (sharp) tongue.” He said: “She will be in Hell.”
He said: “O Messenger of Allaah, So and so (another woman) – and he spoke of how little she fasted and gave charity and prayed – but she gives cheese in charity and she does not annoy her neighbours with her (sharp) tongue.” He said: “She will be in Paradise.”
Narrated by Ahmad in al-Musnad(2/440) and classed as saheeh by al-Albaani in al-Targheeb wa’l-Tarheeb (3/321) and by Shaykh al-Albaani in al-Silsilah al-Saheehah (no. 190).
The same applies to the duty of fasting; the Prophet (peace and blessings of Allaah be upon him)stated that a good attitude is thereward of an accepted fast, and that if a person does not find this benefit, then his fast will notbenefit him at all before Allaah.
It was narrated from Abu Hurayrah (may Allaah be pleasedwith him) that the Messenger of Allaah (peace and blessings of Allaah be upon him) said: “Whoever does not give up false speech and acting upon it, Allaah has no need of his giving up his food and drink.” Narratedby al-Bukhaari (1903). Zakaah is also prescribed to purify the soul, and cleanse it of the stain of sin and spiritual maladies. Allaah says (interpretation of themeaning):
“Take Sadaqah (alms) from their wealth in order to purify them and sanctify them with it”
[al-Tawbah 9:103].
The same applies to the fifth pillar of Islam, namely Hajj. Allaah says (interpretation of themeaning):
“The Hajj (pilgrimage) is (in) the well-known (lunar year) months (i.e. the 10th month, the 11th month and the first ten days of the 12th month of the Islamic calendar, i.e. two months and ten days). So whosoever intendsto perform Hajj therein (by assuming Ihraam), then he should not have sexual relations(with his wife), nor commit sin, nor dispute unjustly during the Hajj”
[al-Baqarah 2:197].
If we were to discuss the great importance of good morals in Islam. Quoting from the Qur'aan and Sunnah, it would take far too long. Ibn al-Qayyim (may Allaah have mercy on him) included a chapter in Madaarij al-Saalikeen (2/307)
