Al-Baqarah 2:223

فِي الدُّنْيَا وَالْآخِرَةِ ۗ وَيَسْأَلُونَكَ عَنِ الْيَتَامَىٰ ۖ قُلْ إِصْلَاحٌ لَّهُمْ خَيْرٌ ۖ وَإِن تُخَالِطُوهُمْ فَإِخْوَانُكُمْ ۚ وَاللَّهُ يَعْلَمُ الْمُفْسِدَ مِنَ الْمُصْلِحِ ۚ وَلَوْ شَاءَ اللَّهُ لَأَعْنَتَكُمْ ۚ إِنَّ اللَّهَ عَزِيزٌ حَكِيمٌ

To this world and the Hereafter. And they ask you about orphans. Say, "Improvement for them is best. And if you mix your affairs with theirs - they are your brothers. And Allah knows the corrupter from the amender. And if Allah had willed, He could have put you in difficulty. Indeed, Allah is Exalted in Might and Wise.

وَلَا تَنكِحُوا الْمُشْرِكَاتِ حَتَّىٰ يُؤْمِنَّ ۚ وَلَأَمَةٌ مُّؤْمِنَةٌ خَيْرٌ مِّن مُّشْرِكَةٍ وَلَوْ أَعْجَبَتْكُمْ ۗ وَلَا تُنكِحُوا الْمُشْرِكِينَ حَتَّىٰ يُؤْمِنُوا ۚ وَلَعَبْدٌ مُّؤْمِنٌ خَيْرٌ مِّن مُّشْرِكٍ وَلَوْ أَعْجَبَكُمْ ۗ أُولَـٰئِكَ يَدْعُونَ إِلَى النَّارِ ۖ وَاللَّهُ يَدْعُو إِلَى الْجَنَّةِ وَالْمَغْفِرَةِ بِإِذْنِهِ ۖ وَيُبَيِّنُ آيَاتِهِ لِلنَّاسِ لَعَلَّهُمْ يَتَذَكَّرُونَ

And do not marry polytheistic women until they believe. And a believing slave woman is better than a polytheist, even though she might please you. And do not marry polytheistic men [to your women] until they believe. And a believing slave is better than a polytheist, even though he might please you. Those invite [you] to the Fire, but Allah invites to Paradise and to forgiveness, by His permission. And He makes clear His verses to the people that perhaps they may remember.

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

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."

وَلَا تَجْعَلُوا اللَّهَ عُرْضَةً لِّأَيْمَانِكُمْ أَن تَبَرُّوا وَتَتَّقُوا وَتُصْلِحُوا بَيْنَ النَّاسِ ۗ وَاللَّهُ سَمِيعٌ عَلِيمٌ

And do not make [your oath by] Allah an excuse against being righteous and fearing Allah and making peace among people. And Allah is Hearing and Knowing.

لَّا يُؤَاخِذُكُمُ اللَّهُ بِاللَّغْوِ فِي أَيْمَانِكُمْ وَلَـٰكِن يُؤَاخِذُكُم بِمَا كَسَبَتْ قُلُوبُكُمْ ۗ وَاللَّهُ غَفُورٌ حَلِيمٌ

Allah 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 Allah is Forgiving and Forbearing.

لِّلَّذِينَ يُؤْلُونَ مِن نِّسَائِهِمْ تَرَبُّصُ أَرْبَعَةِ أَشْهُرٍ ۖ فَإِن فَاءُوا فَإِنَّ اللَّهَ غَفُورٌ رَّحِيمٌ

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, Allah is Forgiving and Merciful.
