The word(s) "till" appears 145 time(s) in 139 verse(s) in Quran in Muhammad Pickthal translation.

(131) Lodge them where ye dwell, according to your wealth, and harass them not so as to straiten life for them. And if they are with child, then spend for them till they bring forth their burden. Then, if they give suck for you, give them their due payment and consult together in kindness; but if ye make difficulties for one another, then let some other woman give suck for him (the father of the child).

(134) Lo! thy Lord knoweth how thou keepest vigil sometimes nearly two-thirds of the night, or (sometimes) half or a third thereof, as do a party of those with thee. Allah measureth the night and the day. He knoweth that ye count it not, and turneth unto you in mercy. Recite, then, of the Qur'an that which is easy for you. He knoweth that there are sick folk among you, while others travel in the land in search of Allah's bounty, and others (still) are fighting for the cause of Allah. So recite of it that which is easy (for you), and establish worship and pay the poor-due, and (so) lend unto Allah a goodly loan.

(135) till the Inevitable came unto us.

(136) Save that which Allah willeth. Lo! He knoweth the disclosed and that which still is hidden;

(137) And by the night when it is stillest,

(138) So when thou art relieved, still toil

(139) Those who disbelieve among the People of the Scripture and the idolaters could not have left off (erring) till the clear proof came unto them,
