The Jews are the Enemies of Jibril
Imam Abu Ja`far bin Jarir At-Tabari said, "The scholars of Tafsir agree that this Ayah (2: 97-98) was revealed in response to the Jews who claimed that Jibril (Gabriel) is an enemy of the Jews and that Mika'il (Michael) is their friend.'' Al-Bukhari said, "Allah said,
[مَن كَانَ عَدُوًّا لِّجِبْرِيلَ]
(Whoever is an enemy of Jibril (let him die in his fury)). `Ikrimah said, "Jibr, Mik and Israf all mean, worshipper, while il means, Allah''. Anas bin Malik said, "When `Abdullah bin Salam heard of the arrival of the Prophet in Al-Madinah, he was working on his land. He came to the Prophet and said, `I am going to ask you about three things which nobody knows except a Prophet. What will be the first portent of the Hour What will be the first meal taken by the people of Paradise Why does a child resemble its father, and why does it resemble its maternal uncle' Allah's Messenger said, (Jibril has just told me the answers.) `Abdullah said, `He (i.e. Jibril), among all the angels, is the enemy of the Jews.' Allah's Messenger recited the Ayah,
[مَن كَانَ عَدُوًّا لِّجِبْرِيلَ فَإِنَّهُ نَزَّلَهُ عَلَى قَلْبِكَ]
(Whoever is an enemy to Jibril (Gabriel) (let him die in his fury), for indeed he has brought it (this Qur'an) down to your heart). Allah's Messenger then said, (The first portent of the Hour will be a fire that will bring together the people from the east to the west; the first meal of the people of Paradise will be the caudate lobe of the liver of fish. As for the child resembling his parents: If a man has sexual intercourse with his wife and his discharge is first, the child will resemble the father. If the woman has a discharge first, the child will resemble her side of the family.) On that `Abdullah bin Salam said, `I testify that there is no deity worthy of worship except Allah and you are the Messenger of Allah.' `Abdullah bin Salam further said, `O Allah's Messenger! The Jews are liars, and if they should come to know about my conversion to Islam before you ask them (about me), they will tell a lie about me.' The Jews came to Allah's Messenger , and `Abdullah went inside the house. Allah's Messenger asked (the Jews), (`What kind of man is `Abdullah bin Salam') They replied, `He is the best among us, the son of the best among us, our master and the son of our master.' Allah's Messenger said, (What do you think if he would embrace Islam) The Jews said, `May Allah save him from it.' Then `Abdullah bin Salam came out in front of them saying, `I testify that none has the right to be worshipped but Allah and that Muhammad is the Messenger of Allah.' Thereupon they said, `He is the evilest among us, and the son of the evilest among us.' And they continued talking badly about him. Ibn Salam said, `This is what I feared, O Messenger of Allah!.''' Only Al-Bukhari recorded this Hadith with this chain of narration. Al-Bukhari and Muslim recorded this Hadith from Anas using another chain of narration.
Some people say that `il' means worshipper while whatever word that is added to it becomes Allah's Name, because `il' is a constant in such conjunction. This is similar to the names `Abdullah, `Abdur-Rahman, `Abdul-Malik, `Abdul-Quddus, `Abdus-Salam, `Abdul-Kafi, `Abdul-Jalil, and so forth. Hence, `Abd' is constant in these compound names, while the remainder differs from name to name. This is the same case with Jibril, Mika'il, `Azra'il, Israfil, and so forth. Allah knows best.
