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) (Using translation from Abū Dāʾūd 265)
إِذَا أَصَابَهَا فِي الدَّمِ فَدِينَارٌ وَإِذَا أَصَابَهَا فِي انْقِطَاعِ الدَّمِ فَنِصْفُ دِينَارٍ
