And they ask you about menstruation. Say, "It is harm, so keep away from wives during menstruation. And do not approach them until they are pure. And when they have purified themselves, then come to them from where Allah has ordained for you. Indeed, Allah loves those who are constantly repentant and loves those who purify themselves."  

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  

Your wives are a place of sowing of seed for you, so come to your place of cultivation however you wish and put forth ˹righteousness˺ for yourselves. And fear Allah and know that you will meet Him. And give good tidings to the believers.  

نِسَاؤُكُمْ حَرْثٌ لَكُمْ فَأْتُوا حَرْثَكُمْ أَنَّىٰ شِئْتُمْ ۖ وَقَدِّمُوا لِأَنْفُسِكُمْ ۚ وَاتَّقُوا اللَّهَ وَاعْلَمُوا أَنَّكُمْ مُلَاقُوهُ ۗ وَبَشِّرِ الْمُؤْمِنِينَ
