Sayyiduna Furat bin Hayan (may Allah be pleased with him) narrates that he was a spy and ally of Abu Sufyan. The Messenger of Allah (peace and blessings be upon him) had given the order to kill him. He passed by a group of the Ansar and said: "I have become a Muslim." One of them said: "O Messenger of Allah! He claims that he has become a Muslim." The Messenger of Allah (peace and blessings be upon him) said: "Some of you are such that we entrust them to their faith. Furat bin Hayan is among them."
