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 what reason have you that you should not fight in the way of Allah and of the weak among the men and the women and the children, (of) those who say: Our Lord! cause us to go forth from this town, whose people are oppressors, and give us from Thee a guardian and give us from Thee a helper.

Surely (as for) those whom the angels cause to die while they are unjust to their souls, they shall say: In what state were you? They shall say: We were weak in the earth. They shall say: Was not Allah's earth spacious, so that you should have migrated therein? So these it is whose abode is hell, and it is an evil resort

And when Musa returned to his people, wrathful (and) in violent grief, he said: Evil is it that you have done after me; did you turn away from the bidding of your Lord? And he threw down the tablets and seized his brother by the head, dragging him towards him. He said: Son of my mother! surely the people reckoned me weak and had well-nigh slain me, therefore make not the enemies to rejoice over me and count me not among the unjust people.

And those who disbelieve say: By no means will we believe in this Quran, nor in that which is before it; and could you see when the unjust shall be made to stand before their Lord, bandying words one with another! Those who were reckoned weak shall say to those who were proud: Had it not been for you we would certainly have been believers.
