Expiation for Intercourse with a Menstruating Woman

Question : Well, if he did it?

Answer : Meaning, if he had intercourse in the private parts, is he sinful or not? He is sinful, meaning he is liable for sin, but he owes an expiation. If he did it, he owes a dinar or half of it as an expiation. What does this indicate? It indicates obligation. It indicates obligation. A dinar or half a dinar is the gold currency, and the weight of the Islamic dinar is one mithqal of gold. So it is obligatory for him to give in charity a dinar of gold or half of it. Is it a choice or a sequence? It is a choice, because the default for [the expiation] is that it is a choice. This is how it came in a hadith narrated by Abu Dawud, and the scholars differed on its authenticity. A group of scholars authenticated it, until Imam Ahmad said, "How good this hadith is." This is the correct narration. Some scholars weakened it and said it is weak, until al-Shafi'i said, "If this hadith were established, I would act upon it."
For this reason, the view that the expiation is obligatory is a unique position in the school of Imam Ahmad (may Allah have mercy on him), and the three Imams all hold that he is sinful without an expiation. However, the hadith is authentic, because all its narrators are trustworthy. And if the hadith is authentic, it does not matter that Imam Ahmad is the only one to report it.
So the correct view is that the expiation is obligatory. At the very least, we say it is obligatory as a precaution. It is obligatory as a precaution. But how much is the dinar? We said it is one mithqal of gold, and the Saudi riyal. Two mithqals.
Except for a little, meaning half a Saudi riyal is sufficient. So he asks about its value in the market. If they say the Saudi riyal is worth a hundred, what is obligatory for him? Fifty, or twenty-five, or approximately twenty-seven. He pays it to the poor, meaning the expiation is paid to the poor. Good.
