I left the afternoon prayer with Abu Bakr al-Siddiq a few nights after the death of the Prophet ﷺ, with Ali

حدثنا محمد بن عبد الله بن الزبير حدثنا عمر بن سعيد عن ابن أبي مليكة أخبرني
خرجت مع أبي بكر الصديق رضي الله عنه من صلاة العصر بعد وفاة النبي ﷺ بليال وعلي عليه السلام يمشي إلى جنبه فمر بحسن بن علي يلعب مع غلمان فاحتمله على رقبته وهو يقول وا بأبي شبه النبي ليس شبيها بعلي قال وعلي يضحك
