Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates that I performed two rak‘ahs of prayer with the Noble Prophet (peace and blessings of Allah be upon him) at Mina, and likewise with Sayyiduna Abu Bakr (may Allah be pleased with him), Sayyiduna Umar (may Allah be pleased with him), and in the early period of the caliphate of Sayyiduna Uthman (may Allah be pleased with him), I performed two rak‘ahs of prayer. Then Sayyiduna Uthman (may Allah be pleased with him) started performing the full (four rak‘ahs) prayer.
