مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحَكَمِ عَنْ عَبْدِ الرَّحْمَنِ بْنِ عُثْمَانَ عَنْ رَجُلٍ مِنْ أَهْلِ الْيَمَامَةِ كَانَ مَعَ أَبِي الْحَسَنِ ( عليه السلام ) أَيَّامَ حُبِسَ بِبَغْدَادَ قَالَ قَالَ لِي أَبُو الْحَسَنِ ( عليه السلام ) إِنَّ اللَّهَ تَعَالَى قَالَ لِنَبِيِّهِ ( صلى الله عليه وآله ) وَ ثِيابَكَ فَطَهِّرْ وَ كَانَتْ ثِيَابُهُ طَاهِرَةً وَ إِنَّمَا أَمَرَهُ بِالتَّشْمِيرِ .
4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from ‘Abd al- Rahman ibn ‘Uthman from a man from the people of al-Yamamah who was with abu al-Hassan , in jail in Baghdad who has said the following: “Abu al-Hassan , once said to me, ‘Allah, most Blessed, most High, has said, to His Holy Prophet, ‘. . . and your clothes cleanse them,’ (74:4) his clothes were clean but He commanded him to raise them instead of keeping them long (that drag on the ground).”’
