Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates concerning the one who comes to his wife while she is menstruating that "he shall give one dinar or half a dinar in charity". This is closer to being correct.
Abd al-Karim bin Abi al-Mukhariq Abu Umayyah is not relied upon as evidence.
