The word(s) "trial" appears 20 time(s) in 20 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) And when We delivered you from Firon's people, who subjected you to severe torment, killing your sons and sparing your women, and in this there was a great trial from your Lord.

(2) And they followed what the Shaitans chanted of sorcery in the reign of Sulaiman, and Sulaiman was not an unbeliever, but the Shaitans disbelieved, they taught men sorcery and that was sent down to the two angels at Babel, Harut and Marut, yet these two taught no man until they had said, "Surely we are only a trial, therefore do not be a disbeliever." Even then men learned from these two, magic by which they might cause a separation between a man and his wife; and they cannot hurt with it any one except with Allah's permission, and they learned what harmed them and did not profit them, and certainly they know that he who bought it should have no share of good in the hereafter and evil was the price for which they sold their souls; had they but known this.

(3) And when We delivered you from Firon's people who subjected you to severe torment, killing your sons and sparing your women, and in this there was a great trial from your Lord.

(4) And Musa chose out of his people seventy men for Our appointment; so when the earthquake overtook them, he said: My Lord! if Thou hadst pleased, Thou hadst destroyed them before and myself (too); wilt Thou destroy us for what the fools among us have done? It is naught but Thy trial, Thou makest err with it whom Thou pleasest and guidest whom Thou pleasest: Thou art our Guardian, therefore forgive us and have mercy on us, and Thou art the best of the forgivers.

(5) And among them there is he who says: Allow me and do not try me. Surely into trial have they already tumbled down, and most surely hell encompasses the unbelievers.

(6) And when Musa said to his people: Call to mind Allah's favor to you when He delivered you from Firon's people, who subjected you to severe torment, and slew your sons and spared your women; and in this there was a great trial from your Lord.

(7) And when We said to you: Surely your Lord encompasses men; and We did not make the vision which We showed you but a trial for men and the cursed tree in the Quran as well; and We cause them to fear, but it only adds to their great inordinacy.

(8) And I do not know if this may be a trial for you and a provision till a time.

(9) And among men is he who serves Allah (standing) on the verge, so that if good befalls him he is satisfied therewith, but if a trial afflict him he turns back headlong; he loses this world as well as the hereafter; that is a manifest loss.

(10) So that He may make what the Shaitan casts a trial for those in whose hearts is disease and those whose hearts are hard; and most surely the unjust are in a great opposition,
