Sayyiduna Shaddad bin Aws (may Allah be pleased with him) narrates: I was going towards Baqi' with the Prophet (peace and blessings of Allah be upon him). This was during the time of the conquest. The Prophet (peace and blessings of Allah be upon him) saw a man who was getting cupped, so the Prophet (peace and blessings of Allah be upon him) said: The one who does cupping and the one who gets cupped, their fast is broken.
