وَيَسْـَٔلُونَكَ عَنِ ٱلْمَحِيضِ ۖ قُلْ هُوَ أَذًۭى فَٱعْتَزِلُوا۟ ٱلنِّسَآءَ فِى ٱلْمَحِيضِ ۖ وَلَا تَقْرَبُوهُنَّ حَتَّىٰ يَطْهُرْنَ ۖ فَإِذَا تَطَهَّرْنَ فَأْتُوهُنَّ مِنْ حَيْثُ أَمَرَكُمُ ٱللَّهُ ۚ إِنَّ ٱللَّهَ يُحِبُّ ٱلتَّوَّٰبِينَ وَيُحِبُّ ٱلْمُتَطَهِّرِينَ ﴿٢٢٢﴾
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 Allāh has ordained for you. Indeed, Allāh loves those who are constantly repentant and loves those who purify themselves."
نِسَآؤُكُمْ حَرْثٌۭ لَّكُمْ فَأْتُوا۟ حَرْثَكُمْ أَنَّىٰ شِئْتُمْ ۖ وَقَدِّمُوا۟ لِأَنفُسِكُمْ ۚ وَٱتَّقُوا۟ ٱللَّهَ وَٱعْلَمُوٓا۟ أَنَّكُم مُّلَـٰقُوهُ ۗ وَبَشِّرِ ٱلْمُؤْمِنِينَ ﴿٢٢٣﴾
Your wives are a place of cultivation [i.e., sowing of seed] for you, so come to your place of cultivation however you wish and put forth [righteousness] for yourselves. And fear Allāh and know that you will meet Him. And give good tidings to the believers.
وَلَا تَجْعَلُوا۟ ٱللَّهَ عُرْضَةًۭ لِّأَيْمَـٰنِكُمْ أَن تَبَرُّوا۟ وَتَتَّقُوا۟ وَتُصْلِحُوا۟ بَيْنَ ٱلنَّاسِ ۗ وَٱللَّهُ سَمِيعٌ عَلِيمٌۭ ﴿٢٢٤﴾
And do not make [your oath by] Allāh an excuse against being righteous and fearing Allāh and making peace among people. And Allāh is Hearing and Knowing.
لَّا يُؤَاخِذُكُمُ ٱللَّهُ بِٱللَّغْوِ فِىٓ أَيْمَـٰنِكُمْ وَلَـٰكِن يُؤَاخِذُكُم بِمَا كَسَبَتْ قُلُوبُكُمْ ۗ وَٱللَّهُ غَفُورٌ حَلِيمٌۭ ﴿٢٢٥﴾
Allāh does not impose blame upon you for what is unintentional in your oaths, but He imposes blame upon you for what your hearts have earned. And Allāh is Forgiving and Forbearing.
لِّلَّذِينَ يُؤْلُونَ مِن نِّسَآئِهِمْ تَرَبُّصُ أَرْبَعَةِ أَشْهُرٍۢ ۖ فَإِن فَآءُو فَإِنَّ ٱللَّهَ غَفُورٌۭ رَّحِيمٌۭ ﴿٢٢٦﴾
For those who swear not to have sexual relations with their wives is a waiting time of four months, but if they return [to normal relations] - then indeed, Allāh is Forgiving and Merciful.
