وَحَدَّثَنِي مَالِكٌ، أَنَّهُ بَلَغَهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ إِنْ كَانَ دَوَاءٌ يَبْلُغُ الدَّاءَ فَإِنَّ الْحِجَامَةَ تَبْلُغُهُ .
Malik related to me that he heard that the Messenger of Allah, (ﷺ), said, "If there is a remedy that will reach the disease, then cupping will reach it."
