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.
