[Machine] Indeed, I will not enforce upon you anything except what I have heard from the Messenger of Allah ﷺ when he addressed us on the day of the Battle of Khaybar. He said, "Whoever believes in Allah and the Last Day should not ride any animal used by Muslims until he has commented upon it, or he said: until it has been tamed." Abu Muhammad said, "I doubt that this could be interpreted as it is." And whoever believes in Allah and the Last Day should not wear a garment taken from the spoils of war until he has purified it.  

إِنِّي لَا أَقُومُ فِيكُمْ إِلَّا مَا سَمِعْتُ رَسُولِ اللَّهِ ﷺ قَامَ فِينَا يَوْمَ خَيْبَرَ حِينَ افْتَتَحْنَاهَا مَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ فَلَا يَرْكَبَنَّ دَابَّةً مِنْ فَيْءِ الْمُسْلِمِينَ حَتَّى إِذَا أَجْحَفَهَا أَوْ قَالَ أَعْجَفَهَا قَالَ أَبُو مُحَمَّد أَنَا أَشُكُّ فِيهِ رَدَّهَا وَمَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ فَلَا يَلْبَسْ ثَوْبًا مِنْ فَيْءِ الْمُسْلِمِينَ حَتَّى إِذَا أَخْلَقَهُ رَدَّهُ فِيهِ
