3a] Is Iblees a jinn or an angel?

3a]
[al-Jinn72;1-2]
In the same soorah, it states that the jinn said:
"'And indeed when we heard the Guidance (this Qur'aan), we believed
therein (Islamic Monotheism), and whosoever believes in his Lord shall
have no fear, either of a decrease in thereward of his good deeds or
an increase in the punishment for his sins. And of us some are
Muslims (who have submitted to Allaah, after listening to this
Qur'aan), and of us some are Al-Qaasitoon (disbelievers those who have
deviated from the Right Path)'..." [al-Jinn 72:13-14]
Ibn Katheer (may Allaah have mercy on him) said in his Tafseer:
Al-Hasan al-Basri said: Iblees was not one of the angels, not even
for a single moment. He is the father of the jinn, just as Adam (peace
be upon him) is the father of mankind. This was narrated by al-Tabari
witha saheeh isnaad (part 3/89).
Some of the scholars said that Iblees was one of theangels, that he
was the peacock of the angels, that he was the one among the angels
who strove the hardest in worship... and other reports, most of which
come from the Israa'eeliyyaat (stories and reports from Jewish
sources), and some of which contradict the clear texts of the Qur'aan.
Ibn Katheer said, explaining this:
A lot of these reports were transmitted from the Salaf, and most of
them come from the Israa'eeliyyaat, which maybe been transmitted in
order to be examined [i.e.,as opposed to being accepted as is]. Allaah
knows best about the veracity or otherwise of many of them. Some of
them are definitely to be rejected, because they go against the truth
which we hold in our hands. In the Qur'aan we have sufficient so that
we have no need of previous reports, because hardly any of them are
free of distortions, with things added or taken away. Many things have
been fabricated in them, for they did not have people who had
memorized things precisely by heart (huffaaz) who could eliminate the
distortions created by extremists andfabricators, unlike this ummah
which has its imaams, scholars, masters,pious and righteous people,
brilliant critics andmen of excellent memory who recorded the hadeeths
and classified them, stating whether they were saheeh (sound),hasan
(good), da'eef (weak), mawdoo' (fabricated), matrook (to be ignored).
They identified the fabricators and liars, and those aboutwhom nothing
was known, and other kinds ofmen (i.e., narrators). All of this
afforded protection tothe Prophet (peace and blessings of Allaah be
upon him), the Seal of the Messengers and the Leader of Mankind, so
thatnothing would be attributed to him falsely and nothing would be
transmitted from him thathe did not say or do. May Allaah be pleased
with them and make them pleased [by rewarding them], and make the
Paradise of al-Firdaws their eternal abode. (Tafseer al-Qur'aan
il-'Azeem, 3/90).
And Allaah knows best.
