Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: A man came to the Prophet (peace and blessings be upon him) and said: O Messenger of Allah! I had intercourse with my wife during her menstruation. So the Prophet (peace and blessings be upon him) instructed him to free a soul (the narrator says:) and in those days the value of a soul was one dinar.
(Allamah al-Haythami says:) Imam al-Tirmidhi has also recorded this narration, and others have recorded it too, but they did not mention freeing a soul.
Imam al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains a narrator, Abd al-Rahman bin Yazid bin Tamim, and he is da'if (weak).
