Sayyiduna Hudhayfah (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings be upon him) said: "After me, follow these two persons: Abu Bakr and Umar, and act upon the guidance of Ammar, and after me, hold firmly to the covenant of Ibn Umm Abd (that is, Sayyiduna Abdullah ibn Mas'ud, may Allah be pleased with him)."
