عَنْ أَبِي سَعِيدٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «ثَلَاثٌ لَا يُفْطِرْنَ الصَّائِمَ الْحِجَامَةُ وَالْقَيْءُ وَالِاحْتِلَامُ» . رَوَاهُ التِّرْمِذِيُّ وَقَالَ: هَذَا حَدِيثٌ غَيْرُ مَحْفُوظٍ وَعَبْدُ الرَّحْمَنِ بْنُ زيد الرَّاوِي يضعف فِي الحَدِيث

Bukhari said without a complete isnad that Ibn ‘Umar used to have himself cupped whan he was fasting. Then he abandoned it and had himself cupped at night.
