Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said: Have yourselves cupped on the 17th, 19th and 21st (of the month); in that case the blood will not surge and kill you. (Allamah al-Haythami says:) I say:
Al-Tirmidhi and others recorded this as a marfu' hadith (attributed to the Prophet), but without these words: "In that case the blood will not surge and kill you."
Al-Bazzar recorded it; its chain contains a narrator, Layth bin Abi Sulaym, who is thiqah (trustworthy), but he is a mudallis (one who conceals defects in his chain).
