“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." (Using translation from Ibn Mājah 2196)  

نَهَى رَسُولُ اللهِ ﷺ عَنْ شِرَاءِ مَا فِي بُطُونِ الْأَنْعَامِ حَتَّى تَضَعَ وَعَنْ مَا فِي ضُرُوعِهَا إِلَّا بِكَيْلٍ وَعَنْ شِرَاءِ الْعَبْدِ وَهُوَ آبِقٌ وَعَنْ شِرَاءِ الْمَغَانِمِ حَتَّى تُقْسَمَ وَعَنْ شِرَاءِ الصَّدَقَاتِ حَتَّى تُقْبَضَ وَعَنْ ضَرْبَةِ الْغَائِصِ  

[Machine] The Messenger of Allah ﷺ prohibited selling what is inside the bellies of animals until they give birth, and what is in their udders, except with a specific measure. He also prohibited the purchase of spoils of war until they are divided, the purchase of donations until they are received, the purchase of a slave while he is in a withering condition, and the striking of joints, and these forbidden matters are included in the prohibited transaction of deception, as stated in the authentic Hadith from the Messenger of Allah ﷺ.  

نَهَى رَسُولُ اللهِ ﷺ عَنْ بَيْعِ مَا فِي بُطُونِ الْأَنْعَامِ حَتَّى تَضَعَ وَعَمَّا فِي ضُرُوعِهَا إِلَّا بِكَيْلٍ وَعَنْ شِرَاءِ الْغَنَائِمِ حَتَّى تُقْسَمَ وَعَنْ شِرَاءِ الصَّدَقَاتِ حَتَّى تُقْبَضَ وَعَنْ شِرَاءِ الْعَبْدِ وَهُوَ آبِقٌ وَعَنْ ضَرْبَةِ الْغَائِصِ وَهَذِهِ الْمَنَاهِي وَإِنْ كَانَتْ فِي هَذَا الْحَدِيثِ بِإِسْنَادٍ غَيْرِ قَوِيٍّ فَهِيَ دَاخِلَةٌ فِي بَيْعِ الْغَرَرِ الَّذِي نُهِيَ عَنْهُ فِي الْحَدِيثِ الثَّابِتِ عَنْ رَسُولِ اللهِ ﷺ  

"نَهَى رَسُولُ الله ﷺ عَنْ بَيعْ الغَنَائِم حَتَّى تُقْسَمَ، وَعَنْ بَيْع الصَّدَقَاتِ حَتَّى تُقْبَضَ، وَعَنْ بَيْع العَبْد وَهُو آبِقٌ، وَعَنْ بَيْع مَا في بُطُونِ الأنْعَام حَتَّى تَضَعَ، وَعَنْ مَا في ضُرُوعِهَا إِلَّا بِكَيْلٍ، وَعَنْ ضَرْبَةِ الغَائِصِ".
