Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: Whoever has intercourse with his wife during her menstruation should give a dinar or half a dinar in charity. Shu’bah said: In my memory, this ruling is marfu’ (attributed to the Prophet), and so-and-so mentioned it as the non-marfu’ statement of Sayyiduna Ibn Abbas (may Allah be pleased with them both). Someone said: Narrate to us from your memory and leave aside the statement of so-and-so. He replied: By Allah, even if I were to meet the lifespan of Nuh (peace be upon him), I would not like to narrate it or remain silent about it. Abu Muhammad Darimi (may Allah have mercy on him) said: Abdul Hamid is Ibn Zayd ibn Abdur Rahman ibn Zayd ibn al-Khattab, who was the governor of Kufa on behalf of Umar ibn Abdul Aziz (may Allah have mercy on him).
