When `Abdullah bin Ubai bin Salul died, Allah's Messenger (ﷺ) was called in order to offer the funeral prayer for him. When Allah's Messenger (ﷺ) got up (to offer the prayer) I jumped towards him and said, "O Allah's Messenger (ﷺ)! Do you offer the prayer for Ibn Ubai although he said so-and-so on such-and-such-a day?" I went on mentioning his sayings. Allah's Messenger (ﷺ) smiled and said, "Keep away from me, O `Umar!" But when I spoke too much to him, he said, "I have been given the choice, and I have chosen (this) ; and if I knew that if I asked forgiveness for him more than seventy times, he would be for given, I would ask it for more times than that." So Allah's Messenger (ﷺ) offered the funeral prayer for him and then left, but he did not stay long before the two Verses of Surat-Bara'a were revealed, i.e.:-- 'And never (O Muhammad) pray for anyone of them that dies.... and died in a state of rebellion.' (9.84) Later I was astonished at my daring to speak like that to Allah's Messenger (ﷺ) and Allah and His Apostle know best.

We were in a Ghazwa (Sufyan once said, in an army) and a man from the emigrants kicked an Ansari man (on the buttocks with his foot). The Ansari man said, "O the Ansar! (Help!)" and the emigrant said. "O the emigrants! (Help!) Allah's Messenger (ﷺ) heard that and said, "What is this call for, which is characteristic of the period of ignorance?" They said, "O Allah's Messenger (ﷺ)! A man from the emigrants kicked one of the Ansar (on the buttocks with his foot)." Allah's Messenger (ﷺ) said, "Leave it (that call) as is a detestable thing." `Abdullah bin Ubai heard that and said, 'Have the (the emigrants) done so? By Allah, if we return Medina, surely, the more honorable will expel therefrom the meaner." When this statement reached the Prophet. `Umar got up an, said, "O Allah's Messenger (ﷺ)! Let me chop off the head of this hypocrite (`Abdullah bin Ubai)!" The Prophet (ﷺ) said "Leave him, lest the people say that Muhammad kills his companions." The Ansar were then more in number than the emigrants when the latter came to Medina, but later on the emigrant increased.

While `Umar was at home in a state of fear, there came Al-`As bin Wail As-Sahmi Abu `Amr, wearing an embroidered cloak and a shirt having silk hems. He was from the tribe of Bani Sahm who were our allies during the pre-Islamic period of ignorance. Al-`As said to `Umar "What is wrong with you?" He said, "Your people claim that they would kill me if I become a Muslim." Al-`As said, "Nobody will harm you after I have given protection to you." So Al-`As went out and met the people streaming in the whole valley. He said, "Where are you going?" They said, "We want Ibn Al-Khattab who has embraced Islam." Al-`As said, "There is no way for anybody to touch him." So the people retreated.
