Sunan Ibn Majah, Book 31, Hadith 3608 (In-Book) ⓘ
Anas bin Malik said: “The Messenger of Allah said: ‘On the night on which I was taken on the Night Journey (Isra’), I did not pass by any group (of angels) but they said to me: “O Muhammad, tell your nation to use cupping.”
حَدَّثَنَا جُبَارَةُ بْنُ الْمُغَلِّسِ، حَدَّثَنَا كَثِيرُ بْنُ سُلَيْمٍ، سَمِعْتُ أَنَسَ بْنَ مَالِكٍ، يَقُولُ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " مَا مَرَرْتُ لَيْلَةَ أُسْرِيَ بِي بِمَلإٍ إِلاَّ قَالُوا يَا مُحَمَّدُ مُرْ أُمَّتَكَ بِالْحِجَامَةِ " .
