Hadith 29:27
Abu Usama narrated to us, from Ismail, from Qays, who said: Sa’d had been suffering from an ulcer in his leg on that day, so he did not go out to the fighting. He said: Then there was a retreat among the people. He said: The wife of Sa’d—who had been married to al-Muthanna ibn Haritha al-Shaybani before him—said, "There is no Muthanna for the horses." So Sa’d slapped her. She said, "Cowardice and jealousy!" He said: Then we defeated them.
حدثنا أبو أسامة عن إسماعيل عن قيس قال كان سعد قد اشتكى قرحة في رجله يومئذ فلم يخرج إلى القتال قال فكانت من الناس انكشافه قال فقالت امرأة سعد وكانت قبله تحت المثنى بن حارثة الشيباني لا مثنى للخيل فلطمها سعد فقالت جبنا وغيرة قال ثم هزمناهم
