[Machine] From the Prophet ﷺ who said, "The best day on which you should have cupping done is on the 17th, 19th, and 21st of the lunar month." He also said, "Whenever I passed by a gathering of angels on the night of my ascension (Isra), they would say to me, 'O Muhammad, you should have cupping done.'"
عَنِ النَّبِيِّ ﷺ قَالَ خَيْرُ يَوْمٍ تَحْتَجِمُونَ فِيهِ سَبْعَ عَشْرَةَ وَتِسْعَ عَشْرَةَ وَإِحْدَى وَعِشْرِينَ وَقَالَ وَمَا مَرَرْتُ بِمَلَإٍ مِنَ الْمَلَائِكَةِ لَيْلَةَ أُسْرِيَ بِي إِلَّا قَالُوا عَلَيْكَ بِالْحِجَامَةِ يَا مُحَمَّدُ
