The word(s) "burden" appears 40 time(s) in 30 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) It is made lawful to you to go into your wives on the night of the fast; they are an apparel for you and you are an apparel for them; Allah knew that you acted unfaithfully to yourselves, so He has turned to you (mercifully) and removed from you (this burden); so now be in contact with them and seek what Allah has ordained for you, and eat and drink until the whiteness of the day becomes distinct from the blackness of the night at dawn, then complete the fast till night, and have not contact with them while you keep to the mosques; these are the limits of Allah, so do not go near them. Thus does Allah make clear His communications for men that they may guard (against evil).

(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) Allah desires that He should make light your burdens, and man is created weak.

(4) And whoever commits a fault or a sin, then accuses of it one innocent, he indeed takes upon himself the burden of a calumny and a manifest sin.

(5) They are losers indeed who reject the meeting of Allah; until when the hour comes upon them all of a sudden they shall say: O our grief for our neglecting it! and they shall bear their burdens on their backs; now surely evil is that which they bear.

(6) And of cattle (He created) beasts of burden and those which are fit for slaughter only; eat of what Allah has given you and do not follow the footsteps of the Shaitan; surely he is your open enemy.

(7) Say: What! shall I seek a Lord other than Allah? And He is the Lord of all things; and no soul earns (evil) but against itself, and no bearer of burden shall bear the burden of another; then to your Lord is your return, so He will inform you of that in which you differed.

(8) Those who follow the Apostle-Prophet, the Ummi, whom they find written down with them in the Taurat and the Injeel (who) enjoins them good and forbids them evil, and makes lawful to them the good things and makes unlawful to them impure things, and removes from them their burden and the shackles which were upon them; so (as for) those who believe in him and honor him and help him, and follow the light which has been sent down with him, these it is that are the successful.

(9) And when it was said to them: Reside in this town and eat from it wherever you wish, and say, Put down from us our heavy burdens: and enter the gate making obeisance, We will forgive you your wrongs: We will give more to those who do good (to others).

(10) He it is Who created you from a single being, and of the same (kind) did He make his mate, that he might incline to her; so when he covers her she bears a light burden, then moves about with it; but when it grows heavy, they both call upon Allah, their Lord: If Thou givest us a good one, we shall certainly be of the grateful ones.
