Sayyiduna Fayruz al-Daylami (may Allah be pleased with him) narrates: I said: O Messenger of Allah, we are those whom you know, our tribe is where you know, and we have settled among those whom you know; so who is our protector? He (peace and blessings be upon him) said: "Allah and His Messenger." I said: That is sufficient for me.
