Surely Allah does not do injustice to the weight of an atom, and if it is a good deed He multiplies it and gives from Himself a great reward.

And when We said to the angels: Make obeisance to Adam; they made obeisance but Iblis (did it not). He was of the jinn, so he transgressed the commandment of his Lord. What! would you then take him and his offspring for friends rather than Me, and they are your enemies? Evil is (this) change for the unjust.
