حدثنا محمد بن أبي عدي عن سعيد يعني ابن أبي عروبة قال حدثني سليمان الناجي عن أبي المتوكل
أن النبي ﷺ صلى بأصحابه ثم جاء فقال نبي الله ﷺ من يتجر على هذا أو يتصدق على هذا فيصلي معه قال فصلى معه رجل
Its isnad is sahih. Sulayman al-Aswad al-Naji Abu Muhammad is truthful (saduq). The hadith was narrated by Daraqutni 1/276 and Bayhaqi 3/69, and Haythami said in 2/46, "The narrators of Ahmad are the narrators of the Sahih."
