Ibn Abbas said: If one has intercourse in the beginning of the menses, (one should give) one dinar; in case one has intercourse towards the end of the menses, then half a dinar (should be given)

Narrated Abdullah ibn Abbas: The Prophet ﷺ said about a person who had intercourse with his wife while she was menstruating: He must give one dinar or half a dinar in alms. Abu Dawud said: The correct version says si: One dinar or half a dinar. Shubah (a narrator) did not sometimes narrate this tradition as a statement of the Prophet ﷺ.

Ibn Abbas reported the Prophet ﷺ as saying; when a man has intercourse with his wife while she is menstruating, he must give half a dinar in alms. Abu Dawud said; Ali bin Budhaimah reported similarly on the authority of Miqsam from the Prophet ﷺ. Al-Awza’I narrated from Yazid bin Abi Malik, from Abd al-Hamid bin Abdur-Rahman from the Prophet ﷺ; He ordered him to give two fifth of a dinar in alms. But this is a chain where two narrators (Miqsam and Ibn Abbas) are missing.

Narrated Abdullah ibn Abbas: The Prophet ﷺ said about a man who has sexual intercourse with a menstruating woman: He should give one or half dinar as sadaqah.
