Surah Al- Baqarah: 256
There is no compulsion in religion. Verily, the Right Path has become distinct from the wrong path. Whoever disbelieves in Taghut and believes in Allah, then he has grasped the most trustworthy handhold that will never break. And Allah is All-Hearer, All-Knower.
Surah Al- Baqarah: 281
And be afraid of the Day when you shall be brought back to Allah. Then every person shall be paid what he earned, and they shall not be dealt with unjustly.
Surah Ali Imran: 30
On the Day when every person will be confronted with all the good he has done, and all the evil he has done, he will wish that there were a great distance between him and his evil. And Allah warns you against Himself and Allah is full of Kindness to the (His) slaves.
