Sura al-Nisāʾ 4:25

وَمَن لَّمْ يَسْتَطِعْ مِنكُمْ طَوْلًا أَن يَنكِحَ ٱلْمُحْصَنَٰتِ ٱلْمُؤْمِنَٰتِ فَمِن مَّا مَلَكَتْ أَيْمَٰنُكُم مِّن فَتَيَٰتِكُمُ ٱلْمُؤْمِنَٰتِ وَٱللَّـهُ أَعْلَمُ بِإِيمَٰنِكُم بَعْضُكُم مِّنۢ بَعْضٍ فَٱنكِحُوهُنَّ بِإِذْنِ أَهْلِهِنَّ وَءَاتُوهُنَّ أُجُورَهُنَّ بِٱلْمَعْرُوفِ مُحْصَنَٰتٍ غَيْرَ مُسَٰفِحَٰتٍ وَلَا مُتَّخِذَٰتِ أَخْدَانٍ فَإِذَآ أُحْصِنَّ فَإِنْ أَتَيْنَ بِفَٰحِشَةٍ فَعَلَيْهِنَّ نِصْفُ مَا عَلَى ٱلْمُحْصَنَٰتِ مِنَ ٱلْعَذَابِ ذَٰلِكَ لِمَنْ خَشِىَ ٱلْعَنَتَ مِنكُمْ وَأَن تَصْبِرُوا۟ خَيْرٌ لَّكُمْ وَٱللَّـهُ غَفُورٌ رَّحِيمٌ

If any of you have not the means wherewith to wed free believing women, they may wed believing girls from among those whom your right hands possess: And Allah hath full knowledge about your faith. Ye are one from another: Wed them with the leave of their owners, and give them their dowers, according to what is reasonable: They should be chaste, not lustful, nor taking paramours: when they are taken in wedlock, if they fall into shame, their punishment is half that for free women. This (permission) is for those among you who fear sin; but it is better for you that ye practise self-restraint. And Allah is Oft-forgiving, Most Merciful.
