Surah No. 2, Al Baqr, part of Ayat No. 286
لاَ يُكَلِّفُ اللّهُ نَفْسًا إِلاَّ وُسْعَهَا لَهَا مَا كَسَبَتْ وَعَلَيْهَا مَا اكْتَسَبَتْ
It is not the policy of Allah to place a burden on any person greater than it can bear. Any one who earned good, will get his reward and any he would come with bad deeds will be punished for what he earned.
Surah No. 23, Al Mominoon, part of Ayat No. 62
وَلَا نُكَلِّفُ نَفْسًا إِلَّا وُسْعَهَا
We do not place a burden on any soul, greater than it can bear:
Narrated Abu Huraira:
The Prophet said, "Religion is very easy and whoever overburdens himself in his religion will not be able to continue in that way. So you should not be extremists, but try to be near to perfection and receive the good tidings that you will be rewarded; and gain strength by worshipping in the mornings, the nights."
