"And they ask you about menstruation. Say, 'It is harm, so keep away from women during menstruation.'" The interpretation of al-Hasan: The devil introduced into the people of the Jahiliyyah regarding women's menstruation a constriction similar to what he introduced to the Magians; they would not sit with them in a house, nor would they eat with them, nor drink. When Islam came, the Muslims asked the Messenger of Allah (ﷺ) about that, so Allah revealed: "Say, 'It is harm'", meaning: filth. "'So keep away from women during menstruation and do not approach them'", meaning: sexual intercourse, "'until they are pure'", meaning: until they see the white discharge. "'And when they have purified themselves'", meaning: have performed the ritual bath, "'then come to them from where Allah has ordained for you.'" Ibn Abbas said: Meaning, from where Allah has commanded you to avoid them. Al-Suddi said: "From where", meaning: in the place where Allah has commanded you; meaning: in the private part. "'Indeed, Allah loves those who are constantly repentant and loves those who purify themselves'" from sins.
﴿وَيَسْأَلُونَكَ عَنِ الْمَحِيضِ قُلْ هُوَ أَذًى فَاعْتَزِلُوا النِّسَاءَ فِي الْمَحِيضِ﴾ ﷺ تَفْسِير الحَسَن: إِن الشَّيْطَان أَدخل على أهل الْجَاهِلِيَّة فِي حيض النِّسَاء من الضّيق مَا أَدخل على الْمَجُوس؛ فَكَانُوا لَا يجالسونهن فِي بَيت، وَلا يَأْكُلُون مَعَهُنَّ، وَلا يشربون؛ فَلَمَّا جَاءَ الإِسْلام سَأَلَ الْمُسلمُونَ رَسُول اللَّهِ ﷺ فِي ذَلِكَ، فَأنْزل اللَّه: ﴿قُلْ هُوَ أَذًى﴾ أَي: قذر ﴿فَاعْتَزِلُوا النِّسَاءَ فِي الْمَحِيض وَلَا تقربوهن﴾ يَعْنِي: المجامعة ﴿حَتَّى يطهرن﴾ يَعْنِي: حَتَّى يريْن الْبيَاض ﴿فَإِذَا تطهرن يَعْنِي: اغْتَسَلْنَ (فَأْتُوهُنَّ مِنْ حَيْثُ أَمركُم الله﴾ قَالَ ابْن عَبَّاس: يَعْنِي: من حَيْثُ أَمركُم الله أَن تجتنبوهن. وَقَالَ السّديّ: (من حَيْثُ) يَعْنِي: فِي حَيْثُ أَمركُم اللَّه؛ يَعْنِي: فِي الْفرج ﴿إِنَّ اللَّهَ يُحِبُّ التَّوَّابِينَ وَيُحب المتطهرين﴾ من الذُّنُوب.
