Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates that the Prophet (peace and blessings be upon him) said: "The fast of the one who cups and the one who is cupped is broken."
Al-Tabarani recorded it in al-Mu'jam al-Awsat. Its chain contains a narrator, al-Hasan bin Abi Ja'far al-Jafri; he has been criticised, though he has also been declared trustworthy.
