"We used to be commanded by the companions of Muhammad ﷺ in battles. And we were in Fars, and the day of slaughter (referring to a specific battle) became difficult for us. So we used to take the elderly and the children by their trunks and ribs. Then a man from Muzaynah tribe stood up among us and said, 'We used to be with the Messenger of Allah ﷺ , and we faced a similar day. So we used to take the elderly and the children by their trunks and ribs.' The Messenger of Allah ﷺ then said, 'Indeed, the trunk fulfills what the rib fulfills.' This hadith is narrated by Ath-Thawri from Asim ibn Kulayb, and the companion mentioned in it is Mujashiq ibn Mas'ud As-Sulami."

أَخْبَرَنَا الشَّيْخُ أَبُو بَكْرِ بْنُ إِسْحَاقَ أَنْبَأَ مُوسَى بْنُ إِسْحَاقَ الْأَنْصَارِيُّ أَنَا عَبْدُ اللَّهِ بْنُ أَبِي شَيْبَةَ ثَنَا عَبْدُ اللَّهِ بْنُ إِدْرِيسَ ثَنَا عَاصِمُ بْنُ كُلَيْبٍ عَنْ أَبِيهِ قَالَ
