From him, from Ibn Ribat from Ibn Udhaynah from Muhammad ibn Muslim, who said: Sometimes I would enter upon Abu Ja‘far عليه السلام after I had prayed Dhuhr and ‘Asr, and Imam عليه السلام would say: "Have you prayed Dhuhr?" And I would say: "Yes, and (also) ‘Asr." Then Imam عليه السلام would say: "I have not yet prayed Dhuhr." He عليه السلام would then rise, calmly and without haste, perform ghusl (ritual bath) or perform wudu’ (ablution), then pray Dhuhr and then pray ‘Asr. And sometimes I would enter upon Him عليه السلام while I had not yet prayed Dhuhr, and He would say: "Have you prayed Dhuhr?" And I would say: "No" Then Imam عليه السلام would say: "I have already prayed Dhuhr and ‘Asr."
