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. Shu'bah (a narrator) did not sometimes narrate this tradition as a statement of the Prophet ﷺ. (Using translation from Abū Dāʾūd 264)  

عَنِ النَّبِيِّ ﷺ فِي الَّذِي يَأْتِي امْرَأَتَهُ وَهِيَ حَائِضٌ قَالَ «يَتَصَدَّقُ بِدِينَارٍ أَوْ بِنِصْفِ دِينَارٍ»  

[Machine] "This is about how my life spanned as long as the life of Noah among his people in this world."  

عَنْ هَذَا وَأَنِّي عُمِّرْتُ فِي الدُّنْيَا عُمَرَ نُوحٍ فِي قَوْمِهِ
