Hadith 4547

Ibn ‘Abbas said the Prophet liked to have himself cupped on the 17th, 19th, and 21st. Baghawi transmitted it in Sharh as-sunna.

وَعَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ يَسْتَحِبُّ الْحِجَامَةَ لِسَبْعَ عَشْرَةَ وَتِسْعَ عَشْرَةَ وَإِحْدَى وَعِشْرِينَ. رَوَاهُ فِي شرح السّنة
