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

(41) So, when they despaired of him, they held a conference in private. The eldest among them said: "Know you not that your father did take an oath from you in Allah's Name, and before this you did fail in your duty with Yusuf (Joseph)? Therefore I will not leave this land until my father permits me, or Allah decides my case (by releasing Benjamin) and He is the Best of the judges.

(42) They said: "By Allah! You will never cease remembering Yusuf (Joseph) until you become weak with old age, or until you be of the dead."

(43) (They were reprieved) until, when the Messengers gave up hope and thought that they were denied (by their people), then came to them Our Help, and whomsoever We willed were rescued. And Our punishment cannot be warded off from the people who are Mujrimun (criminals, sinners, disbelievers, polytheists).

(44) And if there had been a Qur'an with which mountains could be moved (from their places), or the earth could be cloven asunder, or the dead could be made to speak (it would not have been other than this Qur'an). But the decision of all things is certainly with Allah. Have not then those who believed yet known that had Allah willed, He could have guided all mankind? And a disaster will not cease to strike those who disbelieved because of their (evil) deeds or it (i.e. the disaster) settles close to their homes, until the Promise of Allah comes to pass. Certainly, Allah breaks not His Promise.

(45) And worship your Lord until there comes unto you the certainty (i.e. death).

(46) Whoever goes right, then he goes right only for the benefit of his ownself. And whoever goes astray, then he goes astray to his own loss. No one laden with burdens can bear another's burden. And We never punish until We have sent a Messenger (to give warning).

(47) And come not near to the orphan's property except to improve it, until he attains the age of full strength. And fulfil (every) covenant. Verily, the covenant, will be questioned about.

(48) And they say: "We shall not believe in you (O Muhammad صلى الله عليه و سلم), until you cause a spring to gush forth from the earth for us;

(49) "Or you have a house of Zukhruf (like silver and pure gold), or you ascend up into the sky, and even then we will put no faith in your ascension until you bring down for us a Book that we would read." Say (O Muhammad صلى الله عليه و سلم): "Glorified (and Exalted) be my Lord [(Allah) above all that evil they (polytheists) associate with Him]! Am I anything but a man, sent as a Messenger?"

(50) And (remember) when Musa (Moses) said to his boy-servant: "I will not give up (travelling) until I reach the junction of the two seas or (until) I spend years and years in travelling."
