(Menstruation)
They ask you about menstruation: say, “It is harmful; you shall avoid sexual intercourse with the women during menstruation; do not approach them until they are rid of it. Once they are rid of it, you may have intercourse with them in the manner designed by God. God loves the repenters, and He loves those who are clean.”
وَيَسـَٔلونَكَ عَنِ المَحيضِ قُل هُوَ أَذًى فَاعتَزِلُوا النِّساءَ فِى المَحيضِ وَلا تَقرَبوهُنَّ حَتّىٰ يَطهُرنَ فَإِذا تَطَهَّرنَ فَأتوهُنَّ مِن حَيثُ أَمَرَكُمُ اللَّهُ إِنَّ اللَّهَ يُحِبُّ التَّوّٰبينَ وَيُحِبُّ المُتَطَهِّرينَ
