باب مَنْ رَخَّصَ في كِتَابَةِ الْعِلْمِ:Chapter: Permission to Write Knowledge
Hadith 525
أَخْبَرَنَا الْوَلِيدُ بْنُ شُجَاعٍ، حَدَّثَنَا الْمُبَارَكُ بْنُ سَعِيدٍ، قَالَ: "كَانَ سُفْيَانُ يَكْتُبُ الْحَدِيثَ بِاللَّيْلِ فِي الْحَائِطِ، فَإِذَا أَصْبَحَ نَسَخَهُ ثُمَّ حَكَّهُ".
Mubarak bin Saeed narrated: Sufyan used to write hadith on the wall at night, and when morning came, he would copy it and then scrape off what was written on the wall.
