Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates: Sayyiduna Abu Dharr (may Allah be pleased with him) said: I heard the Messenger of Allah (peace and blessings be upon him) say: "The most beloved of you to me and the closest of you to me is the one who comes to me upon the same covenant upon which he parted from me."
