[Machine] The Messenger of Allah ﷺ prohibited eating the meat and drinking the milk of beasts of prey. He also forbade riding them until they are tamed for forty nights. This is not a strong opinion, as Al-Shafi'i referred to it and claimed that it was intended to change their nature from disliked to other than disliked, which is the natural disposition of animals, so that the souls of the prey are not found in their veins and tendons.  

نَهَى رَسُولُ اللهِ ﷺ عَنِ الْجَلَّالَةِ أَنْ يُؤْكَلَ لَحْمُهَا وَيُشْرَبَ لَبَنُهَا وَلَا يُحْمَلَ عَلَيْهَا أَظُنُّهُ قَالَ إِلَّا الْأَدَمُ وَلَا يَرْكَبَهَا النَّاسُ حَتَّى تُعْلَفَ أَرْبَعِينَ لَيْلَةً لَيْسَ هَذَا بِالْقَوِيِّ وَقَدْ أَشَارَ إِلَيْهِ الشَّافِعِيُّ وَزَعَمَ أَنَّهُ أَرَادَ تَغَيُّرَهَا مِنَ الطِّبَاعِ الْمَكْرُوهَةِ إِلَى الطِّبَاعِ غَيْرِ الْمَكْرُوهَةِ الَّتِي هِيَ فِطْرَةُ الدَّوَابِّ حَتَّى لَا تُوجَدَ أَرْوَاحُ الْعَذِرَةِ فِي عِرْقِهَا وَجِرَرِهَا
