البقرة — Al-Baqarah Ayat 222
وَيَسْـَٔلُوْنَكَ عَنِ الْمَحِيْضِ ۗ قُلْ هُوَ اَذًىۙ فَاعْتَزِلُوا النِّسَاۤءَ فِى الْمَحِيْضِۙ وَلَا تَقْرَبُوْهُنَّ حَتّٰى يَطْهُرْنَ ۚ فَاِذَا تَطَهَّرْنَ فَأْتُوْهُنَّ مِنْ حَيْثُ اَمَرَكُمُ اللّٰهُ ۗ اِنَّ اللّٰهَ يُحِبُّ التَّوَّابِيْنَ وَيُحِبُّ الْمُتَطَهِّرِيْنَ
Wa yas'alūnaka ‘anil-maḥīḍ(i), qul huwa ażā(n), fa‘tazilun-nisā'a fil-maḥīḍ(i), wa lā taqrabūhunna ḥattā yaṭhurn(a), fa'iżā taṭahharna fa'tūhunna min ḥaiṡu amarakumullāh(u), innallāha yuḥibbut-tawwābīna wa yuḥibbul-mutaṭahhirīn(a).
"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.""
