The father of Kabshah bint Abi Bakrah (may Allah have mercy on her), Sayyiduna Abu Bakrah (may Allah be pleased with him), used to forbid his family from getting cupped on Tuesday, and he claimed, on the authority of the Messenger of Allah (peace and blessings be upon him), that Tuesday is the day of blood and that in it there is an hour in which blood does not stop.
The prohibition in it is mawquf (a Companion's statement), not marfu', and its chain is not strong. Abu Jurayy Nasr bin Tarif narrated it as marfu' from Abu Hurayrah with two chains of his, but he is matruk (abandoned) and it is not worth mentioning.
