[Machine] I witnessed the battle of Khaybar with my companions, and the Messenger of Allah ﷺ ordered me to carry a sword. As I was carrying it, he said to me, "You will fight with it." It was then said to him, "Indeed, he is a slave who is owned." He then gave me some of the spoils of war. I also presented to him a healing charm that I used to use in the pre-Islamic period to treat the insane. He told me to throw away certain things from it and continue using what remained. Muhammad ibn Zaid said, "I caught up with him while he was still using it to treat the insane."  

شَهِدْتُ مَعَ سَادَتِي خَيْبَرَ فَأَمَرَ بِي رَسُولُ اللهِ ﷺ فَقُلِّدْتُ سَيْفًا فَإِذَا أَنَا أَجُرُّهُ قَالَ فَقِيلَ لَهُ إِنَّهُ عَبْدٌ مَمْلُوكٌ قَالَ فَأَمَرَ لِي بِشَيْءٍ مِنْ خُرْثِيِّ الْمَتَاعِ قَالَ وَعَرَضْتُ عَلَيْهِ رُقْيَةً كُنْتُ أَرْقِي بِهَا الْمَجَانِينَ فِي الْجَاهِلِيَّةِ قَالَ اطْرَحْ مِنْهَا كَذَا وَكَذَا وَارْقِ بِمَا بَقِيَ قَالَ مُحَمَّدُ بْنُ زَيْدٍ وَأَدْرَكْتُهُ وَهُوَ يَرْقِي بِهَا الْمَجَانِينَ
