لَا جُنَاحَ عَلَيْكُمْ اِنْ طَلَّقْتُمُ النِّسَاۤءَ مَا لَمْ تَمَسُّوْهُنَّ اَوْ تَفْرِضُوْا لَهُنَّ فَرِيْضَةً ۖ وَّمَتِّعُوْهُنَّ عَلَى الْمُوْسِعِ قَدَرُهٗ وَعَلَى الْمُقْتِرِ قَدَرُهٗ ۚ مَتَاعًا ۢبِالْمَعْرُوْفِۚ حَقًّا عَلَى الْمُحْسِنِيْنَ ( البقرة: ٢٣٦ )
Laa junaaha 'alaikum in tallaqtumun nisaaa'a maa lam tamassoohunna aw tafridoo lahunna fareedah; wa matti'oona 'alal moosi'i qadaruhoo wa 'alal muqtiri qadaruhoo matta'am bilma'roofi haqqan 'alalmuhsineen (al-Baq̈arah 2:236)
There is no blame upon you if you divorce women you have not touched nor specified for them an obligation. But give them [a gift of] compensation – the wealthy according to his capability and the poor according to his capability – a provision according to what is acceptable, a duty upon the doers of good. (Al-Baqarah  : 236)
1 Mufti Taqi Usmani
There is no liability (of dower) on you if you divorce women when you have not yet touched them, nor fixed for them an amount. So, give them mut‘ah (a gift), a rich man according to his means and a poor one according to his means - a benefit in the recognized manner, an obligation on the virtuous.
