The word(s) "until" appears 90 time(s) in 88 verse(s) in Quran in Mohsin Khan translation.

(51) until, when he reached the setting place of the sun, he found it setting in a spring of black muddy (or hot) water. And he found near it a people. We (Allah) said (by inspiration): "O Dhul-Qarnain! Either you punish them, or treat them with kindness."

(52) until, when he came to the rising place of the sun, he found it rising on a people for whom We (Allah) had provided no shelter against the sun.

(53) until, when he reached between two mountains, he found, before (near) them (those two mountains), a people who scarcely understood a word.

(54) Say (O Muhammad صلى الله عليه وسلم) whoever is in error, the Most Gracious (Allah) will extend (the rope) to him, until, when they see that which they were promised, either the torment or the Hour, they will come to know who is worst in position, and who is weaker in forces. [This is the answer to the question in Verse No.19:73]

(55) They said: "We will not stop worshipping it (i.e. the calf), until Musa (Moses) returns to us."

(56) They speak not until He has spoken, and they act on His Command.

(57) Nay, We gave the luxuries of this life to these men and their fathers until the period grew long for them. See they not that We gradually reduce the land (in their control) from its outlying borders? Is it then they who will overcome?

(58) until, when Ya'juj and Ma'juj (Gog and Magog) are let loose (from their barrier), and they swoop down from every mound.

(59) And those who disbelieved will not cease to be in doubt about it (this Qur'an) until the Hour comes suddenly upon them, or there comes to them the torment of the Day after which there will be no night (i.e. the Day of Resurrection).

(60) until when We seize those of them who lead a luxurious life with punishment: behold they make humble invocation with a loud voice.
