The word(s) "extent" appears 8 time(s) in 8 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) And the mothers should suckle their children for two whole years for him who desires to make complete the time of suckling; and their maintenance and their clothing must be-- borne by the father according to usage; no soul shall have imposed upon it a duty but to the extent of its capacity; neither shall a mother be made to suffer harm on account of her child, nor a father on account of his child, and a similar duty (devolves) on the (father's) heir, but if both desire weaning by mutual consent and counsel, there is no blame on them, and if you wish to engage a wet-nurse for your children, there is no blame on you so long as you pay what you promised for according to usage; and be careful of (your duty to) Allah and know that Allah sees what you do.

(2) Allah does not impose upon any soul a duty but to the extent of its ability; for it is (the benefit of) what it has earned and upon it (the evil of) what it has wrought: Our Lord! do not punish us if we forget or make a mistake; Our Lord! do not lay on us a burden as Thou didst lay on those before us, Our Lord do not impose upon us that which we have not the strength to bear; and pardon us and grant us protection and have mercy on us, Thou art our Patron, so help us against the unbelieving people.

(3) 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;

(4) 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.

(5) They who taunt those of the faithful who give their alms freely, and those who give to the extent of their earnings and scoff at them; Allah will pay them back their scoffing, and they shall have a painful chastisement.

(6) 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.

(7) And the earth, We have made it a wide extent; how well have We then spread (it) out.

(8) Let him who has abundance spend out of his abundance and whoever has his means of subsistence straitened to him, let him spend out of that which Allah has given him; Allah does not lay on any soul a burden except to the extent to which He has granted it; Allah brings about ease after difficulty.
