Surely Allah is not ashamed to set forth any parable-- (that of) a gnat or any thing above that; then as for those who believe, they know that it is the truth from their Lord, and as for those who disbelieve, they say: What is it that Allah means by this parable: He causes many to err by it and many He leads aright by it! but He does not cause to err by it (any) except the transgressors,

And when you said: O Musa! we cannot bear with one food, therefore pray Lord on our behalf to bring forth for us out of what the earth grows, of its herbs and its cucumbers and its garlic and its lentils and its onions. He said: Will you exchange that which is better for that which is worse? Enter a city, so you will have what you ask for. And abasement and humiliation were brought down upon them, and they became deserving of Allah's wrath; this was so because they disbelieved in the communications of Allah and killed the prophets unjustly; this was so because they disobeyed and exceeded the limits.

O you who believe! be not like those who disbelieve and say of their brethren when they travel in the earth or engage in fighting: Had they been with us, they would not have died and they would not have been slain; so Allah makes this to be an intense regret in their hearts; and Allah gives life and causes death and Allah sees what you do.

And certainly We have set forth for men every kind of example in this Quran; and if you should bring them a communication, those who disbelieve would certainly say: You are naught but false claimants.

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.
