[Machine] I found in the book of my uncle Abdulhamid, who narrated to me Aqil, who narrated to me Sa'id bin Sulaiman, who informed him from his father Sulaiman bin Zaid, who narrated from Zaid bin Thabit, who said, "I used to write down the revelation for the Messenger of Allah ﷺ. When it would descend upon him, it would burden him intensely and he would sweat profusely, like pearls. Then it would be taken away from him, and I would enter upon him with a piece of parchment or a bone fragment, and I would write while he dictated to me. I would not stop until my legs were about to break from the weight of the Qur'an, to the extent that I would say, 'I will never be able to walk on my legs again.' And when I would finish, he would say, "Read it." If there was any mistake in it, he would rectify it and then I would take it out to the people."  

وَجَدْتُ فِي كِتَابِ خَالِي عَبْدِ الْحَمِيدِ حَدَّثَنِي عَقِيلُ حَدَّثَنِي سَعِيدُ بْنُ سُلَيْمَانَ أَخْبَرَهُ عَنْ أَبِيهِ سُلَيْمَانَ بْنِ زَيْدٍ عَنْ زَيْدِ بْنِ ثَابِتٍ قَالَ كُنْتُ أَكْتُبُ الْوَحْيَ لِرَسُولِ اللهِ ﷺ وَكَانَ إِذَا نَزَلَ عَلَيْهِ أَخَذَتْهُ بُرَحَاءٌ شَدِيدَةٌ وَعَرِقَ عَرَقًا شَدِيدًا مِثْلَ الْجُمَانِ ثُمَّ سُرِّيَ عَنْهُ فَكُنْتُ أَدْخَلُ عَلَيْهِ بِقِطْعَةِ الْقَتَبِ أَوْ كِسْرَةٍ فَأَكْتُبُ وَهُوَ يُمْلِي عَلَيَّ فَمَا أَفْرَغُ حَتَّى تَكَادَ رِجْلَيَّ تَنْكَسِرُ مِنْ ثِقَلِ الْقُرْآنِ حَتَّى أَقُولَ لَا أَمْشِي عَلَى رِجْلَيَّ أَبَدًا فَإِذَا فَرَغْتُ قَالَ «اقْرَأْهُ» فَإِنْ كَانَ فِيهِ سَقْطٌ أَقَامَهُ ثُمَّ أَخْرَجُ بِهِ إِلَى النَّاسِ
