عَنْ أَبِي سَعِيدٍ
قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «ثَلَاثٌ لَا يُفْطِرْنَ الصَّائِمَ الْحِجَامَةُ وَالْقَيْءُ وَالِاحْتِلَامُ»
cupping, vomiting, and a nocturnal emission. Tirmidhi transmitted it saying this is a tradition which is not regarded, its transmitter Abd ar-Rahman ibn Zaid being declared a weak traditionist.
