The word(s) "air" appears 109 time(s) in 104 verse(s) in Quran in Muhammad Pickthal translation.

(31) And if we cause man to taste some mercy from Us and afterward withdraw it from him, lo! he is despairing, thankless.

(32) (Thus it was) till, when Our commandment came to pass and the oven gushed forth water, We said: Load therein two of every kind, a pair (the male and female), and thy household, save him against whom the word hath gone forth already, and those who believe. And but a few were they who believed with him.

(33) He said: O my people! Bethink you: if I am (acting) on a clear proof from my Lord and He sustaineth me with fair sustenance from Him (how can I concede aught to you)? I desire not to do behind your backs that which I ask you not to do. I desire naught save reform so far as I am able. My welfare is only in Allah. In Him I trust and unto Him I turn (repentant).

(34) So, When they despaired of (moving) him, they conferred together apart. The eldest of them said: Know ye not how your father took an undertaking from you in Allah's name and how ye failed in the case of Joseph aforetime? Therefore I shall not go forth from the land until my father giveth leave or Allah judgeth for me. He is the Best of Judges.

(35) Go, O my sons, and ascertain concerning Joseph and his brother, and despair not of the Spirit of Allah. Lo! none despaireth of the Spirit of Allah save disbelieving folk.

(36) Till, when the messengers despaired and thought that they were denied, then came unto them Our help, and whom We would was saved. And Our wrath cannot be warded from the guilty.

(37) Is He Who is aware of the deserts of every soul (as he who is aware of nothing)? Yet they ascribe unto Allah partners. Say: Name them. Is it that ye would inform Him of something which He knoweth not in the earth? Or is it but a way of speaking? Nay but their contrivance is made seeming fair for those who disbelieve and they are kept from the right road. He whom Allah sendeth astray, for him there is no guide.

(38) As they come hurrying on in fear, their heads upraised, their gaze returning not to them, and their hearts as air.

(39) They said: We bring thee good tidings in truth. So be not thou of the despairing.

(40) He said: And who despaireth of the mercy of his Lord save those who are astray?
