Sayyiduna Anas (may Allah be pleased with him) narrates this saying of the Prophet (peace and blessings be upon him): "The fast of the one who cups and the one who is cupped is broken."
Al-Bazzar recorded it. Its chain contains a narrator, Malik bin Sulayman; the hadith scholars declared him da'if (weak) on account of this hadith.
