Sayyiduna Abu Umamah (Sayyiduna Sa’d bin Sahl, may Allah be pleased with him) used to say: We performed the Zuhr prayer with ‘Umar bin ‘Abdul ‘Aziz (may Allah have mercy on him), then we went out and presented ourselves before Sayyiduna Anas bin Malik (may Allah be pleased with him) and saw that he was performing prayer. I asked,“O honorable uncle, which prayer have you just performed?”He replied,“The ‘Asr prayer, and at this very time we used to perform this prayer with the Messenger of Allah (peace and blessings of Allah be upon him) as well.”
