Appears 9 times in the Quran. (Root: ليس)
  1. It is not righteousness that you turn your faces towards the East and the West, but righteousness is this that one should believe in Allah and the last day and the angels and the Book and the prophets, and give away wealth out of love for Him to the near of kin and the orphans and the needy and the wayfarer and the beggars and for (the emancipation of) the captives, and keep up prayer and pay the poor-rate; and the performers of their promise when they make a promise, and the patient in distress and affliction and in time of conflicts-- these are they who are true (to themselves) and these are they who guard (against evil).

  2. To make them walk in the right way is not incumbent on you, but Allah guides aright whom He pleases; and whatever good thing you spend, it is to your own good; and you do not spend but to seek Allah's pleasure; and whatever good things you spend shall be paid back to you in full, and you shall not be wronged.

  3. (This) shall not be in accordance with your vain desires nor in accordance with the vain desires of the followers of the Book; whoever does evil, he shall be requited with it, and besides Allah he will find for himself neither a guardian nor a helper.

  5. It is no sin in you that you enter uninhabited houses wherein you have your necessaries; and Allah knows what you do openly and what you hide.

  6. There is no blame on the blind man, nor is there blame on the lame, nor is there blame on the sick, nor on yourselves that you eat from your houses, or your fathers' houses or your mothers' houses, or your brothers' houses, or your sisters' houses, or your paternal uncles' houses, or your paternal aunts' houses, or your maternal uncles' houses, or your maternal aunts' houses, or what you possess the keys of, or your friends' (houses). It is no sin in you that you eat together or separately. So when you enter houses, greet your people with a salutation from Allah, blessed (and) goodly; thus does Allah make clear to you the communications that you may understand.

  7. There is no harm in the blind, nor is there any harm in the lame, nor is there any harm in the sick (if they do not go forth); and whoever obeys Allah and His Messenger, He will cause him to enter gardens beneath which rivers flow, and whoever turns back, He will punish him with a painful punishment.

  8. And that man shall have nothing but what he strives for-

  9. They shall have no food but of thorns,
