Appears 3 times in the Quran. (Root: كلف)
  1. And do not approach the property of the orphan except in the best manner until he attains his maturity, and give full measure and weight with justice-- We do not impose on any soul a duty except to the extent of its ability; and when you speak, then be just though it be (against) a relative, and fulfill Allah's covenant; this He has enjoined you with that you may be mindful;

  2. And (as for) those who believe and do good We do not impose on any soul a duty except to the extent of its ability-- they are the dwellers of the garden; in it they shall abide.

  3. And We do not lay on any soul a burden except to the extent of its ability, and with Us is a book which speaks the truth, and they shall not be dealt with unjustly.
