It is narrated from Hazrat Firoz (may Allah be pleased with him) that the people of his tribe became Muslim, and he himself was among them. They sent word to the Prophet (peace and blessings be upon him) to inform him of their pledge of allegiance and acceptance of Islam. The Prophet (peace and blessings be upon him) accepted their pledge and Islam. They said, "O Messenger of Allah! (peace and blessings be upon him) You know which tribe we belong to, and you also know where we have come from. Now that we have become Muslim, who is our guardian?" The Prophet (peace and blessings be upon him) said, "Allah and His Messenger (peace and blessings be upon him)." They said, "This is enough for us and we are pleased with it."
