Ibn 'Abbas narrated that the Messenger of Allah (ﷺ) said:

"Indeed the best of what you treat is As-Sa'ut, Al-Ladud, cupping and laxatives.' So when the Messenger of Allah (ﷺ) was suffering his companions treated him with Al-Ladud, and when they were finished he said: 'Treat them with Al-Ladud.' So all of them except Al-Abbas were treated with Al-Ladud."(Daif)

حَدَّثَنَا مُحَمَّدُ بْنُ مَدُّويَهْ، قال حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ حَمَّادٍ الشُّعَيْثِيُّ، قال حَدَّثَنَا عَبَّادُ بْنُ مَنْصُورٍ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ إِنَّ خَيْرَ مَا تَدَاوَيْتُمْ بِهِ السَّعُوطُ وَاللَّدُودُ وَالْحِجَامَةُ وَالْمَشِيُّ ‏"‏ ‏.‏ فَلَمَّا اشْتَكَى رَسُولُ اللَّهِ صلى الله عليه وسلم لَدَّهُ أَصْحَابُهُ فَلَمَّا فَرَغُوا قَالَ ‏"‏ لُدُّوهُمْ ‏"‏ ‏.‏ قَالَ فَلُدُّوا كُلُّهُمْ غَيْرَ الْعَبَّاسِ ‏.‏
