[Machine] The Qur'ans were not sold. A man would come with a piece of paper to the Prophet ﷺ , and the man would stand up, calculate, and then write. Then another man would stand up and write until they finished the Qur'an.
كَانَتِ الْمَصَاحِفُ لَا تُبَاعُ كَانَ الرَّجُلُ يَأْتِي بِوَرَقَةٍ عِنْدَ النَّبِيِّ ﷺ فَيَقُومُ الرَّجُلُ فَيَحْتَسِبُ فَيَكْتَبُ ثُمَّ يَقُومُ آخَرُ فَيَكْتُبُ حَتَّى يُفْرَغَ مِنَ الْمُصْحَفِ
