The word(s) "heavy" appears 11 time(s) in 10 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) O you who believe! do not make your charity worthless by reproach and injury, like him who spends his property to be seen of men and does not believe in Allah and the last day; so his parable is as the parable of a smooth rock with earth upon it, then a heavy rain falls upon it, so it leaves it bare; they shall not be able to gain anything of what they have earned; and Allah does not guide the unbelieving people.

(2) And the parable of those who spend their property to seek the pleasure of Allah and for the certainty 'of their souls is as the parable of a garden on an elevated ground, upon which heavy rain falls so it brings forth its fruit twofold but if heavy rain does not fall upon it, then light rain (is sufficient); and Allah sees what you do.

(3) And the measuring out on that day will be just; then as for him whose measure (of good deeds) is heavy, those are they who shall be successful;

(4) 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).

(5) 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.

(6) Go forth light and heavy, and strive hard in Allah's way with your property and your persons; this is better for you, if you know.

(7) He it is Who shows you the lightning causing fear and hope and (Who) brings up the heavy cloud.

(8) And they carry your heavy loads to regions which you could not reach but with distress of the souls; most surely your Lord is Compassionate, Merciful.

(9) Surely with Us are heavy fetters and a flaming fire,

(10) Then as for him whose measure of good deeds is heavy,
