When the Messenger of Allah ﷺ became gravely ill, I was with him among a group of Muslims. Bilal called him to the prayer, and he said, "Tell someone to lead the people in prayer."So Abdullah bin Zama went out and found Umar among the people, as Abu Bakr was absent. I said, "Umar, get up and lead the people in prayer."So he stepped forward and said the takbir. When the Messenger of Allah ﷺ heard his voice, and Umar was a man with a loud voice, he said, "Where is Abu Bakr? Allah refuses that, and so do the Muslims. Allah refuses that, and so do the Muslims."So he sent for Abu Bakr, who came after Umar had completed that prayer, and then Abu Bakr led the people in prayer.
حدثنا عبد الله بن محمد النفيلي حدثنا محمد بن سلمة عن محمد بن إسحق قال حدثني الزهري حدثني عبد الملك بن أبي بكر بن عبد الرحمن بن الحارث بن هشام عن أبيه
لما استعز برسول الله ﷺ وأنا عنده في نفر من المسلمين دعاه بلال إلى الصلاة فقال مروا من يصلي للناس فخرج عبد الله بن زمعة فإذا عمر في الناس وكان أبو بكر غائبا فقلت يا عمر قم فصل بالناس فتقدم فكبر فلما سمع رسول الله ﷺ صوته وكان عمر رجلا مجهرا قال فأين أبو بكر يأبى الله ذلك والمسلمون يأبى الله ذلك والمسلمون فبعث إلى أبي بكر فجاء بعد أن صلى عمر تلك الصلاة فصلى بالناس
