Narrated `Abdullah bin Mus'ud
We have been powerful since `Umar embraced Islam.
Narrated `Abdullah bin `Umar
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.
Narrated `Abdullah bin `Umar
When `Umar embraced Islam, all The (disbelieving) people gathered around his home and said, "`Umar has embraced Islam." At that time I was still a boy and was on the roof of my house. There came a man wearing a cloak of Dibaj (i.e. a kind of silk), and said, "`Umar has embraced Islam. Nobody can harm him for I am his protector." I then saw the people going away from `Umar and asked who the man was, and they said, "Al-`As bin Wail."
Narrated `Abdullah bin `Umar
I never heard `Umar saying about something that he thought it would be so-and-so, but he was quite right. Once, while `Umar was sitting, a handsome man passed by him, `Umar said, "If I am not wrong, this person is still on his religion of the pre-lslamic period of ignorance or he was their foreteller. Call the man to me." When the man was called to him, he told him of his thought. The man said, "I have never seen such a day on which a Muslim is faced with such an accusation." `Umar said, "I am determined that you should tell me the truth." He said, "I was a foreteller in the pre-lslamic period of ignorance." Then `Umar said, "Tell me the most astonishing thing your female Jinn has told you of." He said, "One-day while I was in the market, she came to me scared and said, 'Haven't you seen the Jinns and their despair and they were overthrown after their defeat (and prevented from listening to the news of the heaven) so that they (stopped going to the sky and) kept following camel-riders (i.e. 'Arabs)?" `Umar said, "He is right." and added, "One day while I was near their idols, there came a man with a calf and slaughtered it as a sacrifice (for the idols). An (unseen) creature shouted at him, and I have never heard harsher than his voice. He was crying, 'O you bold evil-doer! A matter of success! An eloquent man is saying: None has the right to be worshipped except you (O Allah).' On that the people fled, but I said, 'I shall not go away till I know what is behind this.' Then the cry came again: 'O you bold evil-doer! A matter of success! An eloquent man is saying: None has the right to be worshipped except Allah.' I then went away and a few days later it was said, "A prophet has appeared."
Narrated Qais
I heard Sa`id bin Zaid saying to the people, "If you but saw me and `Umar's sister tied and forced by `Umar to leave Islam while he was not yet a Muslim. And if the mountain of Uhud could move from its place for the evil which you people have done to `Uthman, it would have the right to do that."
