It did not beseem the people of Medina and those round about them of the dwellers of the desert to remain behind the Messenger of Allah, nor should they desire (anything) for themselves in preference to him; this is because there afflicts them not thirst or fatigue or hunger in Allah's way, nor do they tread a path which enrages the unbelievers, nor do they attain from the enemy what they attain, but a good work is written down to them on account of it; surely Allah does not waste the reward of the doers of good;

To Him is your return, of all (of you); the promise of Allah (made) in truth; surely He begins the creation in the first mstance, then He reproduces it, that He may with justice recompense those who believe and do good; and (as for) those who disbelieve, they shall have a drink of hot water and painful punishment because they disbelieved.

And (as for) those who believe and do good, We will most certainly do away with their evil deeds and We will most certainly reward them the best of what they did.

Allah sets forth an example to those who disbelieve the wife of Nuh and the wife of Lut: they were both under two of Our righteous servants, but they acted treacherously towards them so they availed them naught against Allah, and it was said: Enter both the fire with those who enter.
