The word(s) "main" appears 48 time(s) in 48 verse(s) in Quran in Muhammad Habib Shakir translation.

(21) The way (to blame) is only against those who ask permission of you though they are rich; they have chosen to be with those who remained behind, and Allah has set a seal upon their hearts so they do not know.

(22) It did not beseem the people of Medina and those round about them of the dwellers of the desert to remain behind the Apostle of Allah, nor should they desire (anything) for themselves in preference to him; this is because there afflicts them not thirst or fatigue or hunger in Allah's way, nor do they tread a path which enrages the unbelievers, nor do they attain from the enemy what they attain, but a good work is written down to them on account of it; surely Allah does not waste the reward of the doers of good;

(23) Say: I do not control for myself any harm, or any benefit except what Allah pleases; every nation has a term; when their term comes, they shall not then remain behind for an hour, nor can they go before (their time).

(24) And recite to them the story of Nuh when he said to his people: O my people! if my stay and my reminding (you) by the communications of Allah is hard on you-- yet on Allah do I rely-- then resolve upon your affair and (gather) your associates, then let not your affair remain dubious to you, then have it executed against me and give me no respite:

(25) What remains with Allah is better for you if you are believers, and I am not a keeper over you.

(26) And he said to him whom he knew would be delivered of the two: Remember me with your lord; but the Shaitan caused him to forget mentioning (it) to his lord, so he remained in the prison a few years.

(27) Except his wife; We ordained that she shall surely be of those who remain behind.

(28) Then We raised them up that We might know which of the two parties was best able to compute the time for which they remained.

(29) And they remained in their cave three hundred years and (some) add (another) nine.

(30) Say: Allah knows best how long they remained; to Him are (known) the unseen things of the heavens and the earth; how clear His sight and how clear His hearing! There is none to be a guardian for them besides Him, and He does not make any one His associate in His Judgment.
