Surah At-Talaq (The Divorce), Verse 7

لِیُنْفِقْ ذُوْ سَعَةٍ مِّنْ سَعَتِهٖ وَمَنْ قُدِرَ عَلَیْهِ رِزْقُهٗ فَلْیُنْفِقْ مِمَّاۤ اٰتٰىهُ اللّٰهُ لَا یُكَلِّفُ اللّٰهُ نَفْسًا اِلَّا مَاۤ اٰتٰىهَا سَیَجْعَلُ اللّٰهُ بَعْدَ عُسْرٍ یُّسْرًا 

Liyunfiq zoo sa'atim min sa'atih; wa man qudira 'alaihi rizquhoo falyunfiq mimmaaa aataahul laah; laa yukalliful laahu nafsan illaa maaa aataahaa; sa yaj'alul laahu ba'da'usriny yusraa

“Let the man of means spend according to his means: and the man whose resources are restricted, let him spend according to what Allah has given him. Allah puts no burden on any person beyond what He has given him. After a difficulty, Allah will soon grant relief.”
