Surat Al-Baqara (The Cow) - البقرة

لَّا جُنَاحَ عَلَيْكُمْ إِن طَلَّقْتُمُ ٱلنِّسَآءَ مَا لَمْ تَمَسُّوهُنَّ أَوْ تَفْرِضُوا۟ لَهُنَّ فَرِيضَةً وَمَتِّعُوهُنَّ عَلَى ٱلْمُوسِعِ قَدَرُهُۥ وَعَلَى ٱلْمُقْتِرِ قَدَرُهُۥ مَتَٰعًۢا بِٱلْمَعْرُوفِ حَقًّا عَلَى ٱلْمُحْسِنِينَ ﴿٢٣٦﴾

There is no blame on you if you divorce women when you have not touched them or appointed for them a portion, and make provision for them, the wealthy according to his means and the straitened in circumstances according to his means, a provision according to usage; (this is) a duty on the doers of good (to others).
