The word(s) "weigh" appears 19 time(s) in 19 verse(s) in Quran in Muhammad Habib Shakir translation.

(11) Surely Qaroun was of the people of Musa, but he rebelled against them, and We had given him of the treasures, so much so that his hoards of wealth would certainly weigh down a company of men possessed of great strength. When his people said to him: Do not exult, surely Allah does not love the exultant;

(12) O my son! surely if it is the very weight of the grain of a mustard-seed, even though it is in (the heart of) rock, or (high above) in the heaven or (deep down) in the earth, Allah will bring it (to light); surely Allah is Knower of subtleties, Aware;

(13) And those who disbelieve say: The hour shall not come upon us. Say: Yea! by my Lord, the Knower of the unseen, it shall certainly come upon you; not the weight of an atom becomes absent from Him, in the heavens or in the earth, and neither less than that nor greater, but (all) is in a clear book

(14) Say: Call upon those whom you assert besides Allah; they do not control the weight of an atom in the heavens or in the earth nor have they any partnership in either, nor has He among them any one to back (Him) up.

(15) And a burdened soul cannot bear the burden of another and if one weighed down by burden should cry for (another to carry) its burden, not aught of it shall be carried, even though he be near of kin. You warn only those who fear their Lord in secret and keep up prayer; and whoever purifies himself, he purifies himself only for (the good of) his own soul; and to Allah is the eventual coming.

(16) Surely We will make to light upon you a weighty Word.

(17) But when they measure out to others or weigh out for them, they are deficient.

(18) So. he who has done an atom's weight of good shall see it

(19) And he who has done an atom's weight of evil shall see it.
