The word(s) "leave" appears 88 time(s) in 78 verse(s) in Quran in Muhammad Pickthal translation.

(31) Allah forgive thee (O Muhammad)! Wherefor didst thou grant them leave ere those who told the truth were manifest to thee and thou didst know the liars?

(32) Those who believe in Allah and the Last Day ask no leave of thee lest they should strive with their wealth and their lives. Allah is Aware of those who keep their duty (unto Him).

(33) They alone ask leave of thee who believe not in Allah and the Last Day, and whose hearts feel doubt, so in their doubt they waver.

(34) Of them is he who saith: Grant me leave (to stay at home) and tempt me not. Surely it is into temptation that they (thus) have fallen. Lo! hell verily is all around the disbelievers.

(35) If Allah bring thee back (from the campaign) unto a party of them and they ask of thee leave to go out (to fight), then say unto them: Ye shall never more go out with me nor fight with me against a foe. Ye were content with sitting still the first time. So sit still, with the useless.

(36) And when a surah is revealed (which saith): Believe in Allah and strive along with His messenger, the men of wealth among them still ask leave of thee and say: Suffer us to be with those who sit (at home).

(37) The road (of blame) is only against those who ask for leave of thee (to stay at home) when they are rich. They are content to be with the useless. Allah hath sealed their hearts so that they know not.

(38) That which Allah leaveth with you is better for you if ye are believers; and I am not a keeper over you.

(39) They said: O Shu'eyb! Doth thy way of prayer command thee that we should forsake that which our fathers (used to) worship, or that we (should leave off) doing what we will with our own property. Lo! thou art the mild, the guide to right behaviour.

(40) He said: Ye shall sow seven years as usual, but that which ye reap, leave it in the ear, all save a little which ye eat.
