He (may Allah be pleased with him) says that one day Hazrat Mu’adh (may Allah be pleased with him) came to me while I had with me a Jew who had become Muslim and then reverted from Islam to Judaism. Upon this, he (may Allah be pleased with him) said: I will never dismount at your place until you kill him. Hajjaj narrates that Hazrat Qatadah (may Allah be pleased with him) informed me that Hazrat Abu Musa had invited that Jew for forty days.

Hazrat Uthman (may Allah be pleased with him) wrote back in reply, instructing him to invite these people to Islam. So, whoever among them bears witness that there is no deity worthy of worship except Allah and that indeed Muhammad (peace and blessings be upon him) is the Messenger of Allah, and abandons disbelief to embrace faith, then accept their faith and let them go their way.

We captured him. He, may Allah be pleased with him, asked: What did you do with him? They said: We killed him. He, may Allah be pleased with him, said: Why did you not put him in a house and then lock the door on him, that is, imprison him, and give him a little food daily, then ask him to repent three times, and if he repented, then fine, otherwise you would have killed him?! Then he, may Allah be pleased with him, said: O Allah! I am neither a witness over them nor did I order them, and when this matter reached me, I was not pleased with it.
