It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) was asked about a man who has intercourse with his wife while she is menstruating, and he (peace and blessings be upon him) ordered him to give "one dinar or half a dinar in charity." His hearing of it from Abd al-Hamid is not established.
