حَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا هَاشِمٌ، - يَعْنِي ابْنَ الْقَاسِمِ - عَنْ سُلَيْمَانَ، عَنْ ثَابِتٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ دَخَلَ عَلَيْنَا النَّبِيُّ صلى الله عليه وسلم فَقَالَ عِنْدَنَا فَعَرِقَ وَجَاءَتْ أُمِّي بِقَارُورَةٍ فَجَعَلَتْ تَسْلُتُ الْعَرَقَ فِيهَا فَاسْتَيْقَظَ النَّبِيُّ صلى الله عليه وسلم فَقَالَ ‏"‏ يَا أُمَّ سُلَيْمٍ مَا هَذَا الَّذِي تَصْنَعِينَ ‏"‏ ‏.‏ قَالَتْ هَذَا عَرَقُكَ نَجْعَلُهُ فِي طِيبِنَا وَهُوَ مِنْ أَطْيَبِ الطِّيبِ ‏.‏
