Narrated Ibn `Abbas: The Prophet was cupped and he paid the wages to the one who had cupped him and then took Su'ut (Medicine sniffed by nose).
حَدَّثَنَا مُعَلَّى بْنُ أَسَدٍ، حَدَّثَنَا وُهَيْبٌ، عَنِ ابْنِ طَاوُسٍ، عَنْ أَبِيهِ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ عَنِ النَّبِيِّ صلى الله عليه وسلم احْتَجَمَ وَأَعْطَى الْحَجَّامَ أَجْرَهُ وَاسْتَعَطَ.
