It was narrated that Abu Sa'eed Al-Khudri said:
“The Messenger of Allah ﷺ forbade selling what is in the wombs of cattle until they give birth, and selling what is in their udders unless it is measured out, and selling a slave who has fled, and selling spoils of war until it has been distributed, and selling Sadaqah until it has been received, and what a diver is going to bring up."

حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ، حَدَّثَنَا حَاتِمُ بْنُ إِسْمَاعِيلَ، حَدَّثَنَا جَهْضَمُ بْنُ عَبْدِ اللَّهِ الْيَمَامِيُّ، عَنْ مُحَمَّدِ بْنِ إِبْرَاهِيمَ الْبَاهِلِيِّ، عَنْ مُحَمَّدِ بْنِ زَيْدٍ الْعَبْدِيِّ، عَنْ شَهْرِ بْنِ حَوْشَبٍ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، قَالَ نَهَى رَسُولُ اللَّهِ ـ ﷺ ـ عَنْ شِرَاءِ مَا فِي بُطُونِ الأَنْعَامِ حَتَّى تَضَعَ وَعَمَّا فِي ضُرُوعِهَا إِلاَّ بِكَيْلٍ وَعَنْ شِرَاءِ الْعَبْدِ وَهُوَ آبِقٌ وَعَنْ شِرَاءِ الْمَغَانِمِ حَتَّى تُقْسَمَ وَعَنْ شِرَاءِ الصَّدَقَاتِ حَتَّى تُقْبَضَ وَعَنْ ضَرْبَةِ الْغَائِصِ .
