Narrated Thabit Al-Bunani:

Anas bin Malik was asked whether they disliked the cupping for a fasting person. He replied in the negative and said, "Only if it causes weakness."

حَدَّثَنَا آدَمُ بْنُ أَبِي إِيَاسٍ، حَدَّثَنَا شُعْبَةُ، قَالَ سَمِعْتُ ثَابِتًا الْبُنَانِيَّ، يَسْأَلُ أَنَسَ بْنَ مَالِكٍ ـ رضى الله عنه ـ أَكُنْتُمْ تَكْرَهُونَ الْحِجَامَةَ لِلصَّائِمِ قَالَ لاَ‏.‏ إِلاَّ مِنْ أَجْلِ الضَّعْفِ‏.‏ وَزَادَ شَبَابَةُ حَدَّثَنَا شُعْبَةُ عَلَى عَهْدِ النَّبِيِّ صلى الله عليه وسلم‏.‏

Hijaamah (wet cupping therapy) is one of the ancient forms of alternative medicine used to remove bad blood from the body. In this hadeeth,the Taab’iee Thaabit Al-Bunaaneeinforms us that Anas ibn Maalik (may Allah be pleased with him) was asked whether they believed that Hijaamah therapy was disliked for a fasting person during the lifetime of the Prophet ﷺ. Anas (may Allah be pleased with him) clarifiedthat it was held as non-prohibitivelydisliked(Makrooh Tanzeehan) rather than prohibitively disliked (Makrooh Tahreeman), because it may cause fatigue during fasting, possibly drainingthe fasting person and requiringhim to getnutrients into his body (i.e., break his fast). .
