Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) 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 and al-Tabarani in al-Mu'jam al-Kabir recorded it. Al-Bazzar's narrators have been declared trustworthy, except for Fitr bin Khalifah, whose case is different: he has been criticised, though he is thiqah (trustworthy).
