سورة البقرة

وَيَسْأَلُونَكَ عَنِ الْمَحِيضِ ۖ قُلْ هُوَ أَذًى فَاعْتَزِلُوا النِّسَاءَ فِي الْمَحِيضِ ۖ وَلَا تَقْرَبُوهُنَّ حَتَّىٰ يَطْهُرْنَ ۖ فَإِذَا تَطَهَّرْنَ فَأْتُوهُنَّ مِنْ حَيْثُ أَمَرَكُمُ اللَّهُ ۚ إِنَّ اللَّهَ يُحِبُّ التَّوَّابِينَ وَيُحِبُّ الْمُتَطَهِّرِينَ ﴿٢٢٢

Surah al-Baqarah

222. And they ask you about menstruation: say, “It is harmful, so stay away from women during menstruation. And do not approach them until they have become pure. Once they have become pure, approach them in the manner Allah has directed you.” Allah loves the repentant, and He loves those who keep clean.”
