The word(s) "aileth" appears 32 time(s) in 32 verse(s) in Quran in Muhammad Pickthal translation.

(21) And they say: What aileth us that we behold not men whom we were wont to count among the wicked?

(22) But those who keep their duty to their Lord, for them are lofty halls with lofty halls above them, built (for them), beneath which rivers flow. (It is) a promise of Allah. Allah faileth not His promise.

(23) And, O my people! What aileth me that I call you unto deliverance when ye call me unto the Fire?

(24) The day when their excuse availeth not the evil-doers, and theirs is the curse, and theirs the ill abode.

(25) And how many angels are in the heavens whose intercession availeth naught save after Allah giveth leave to whom He chooseth and accepteth.

(26) What aileth you that ye believe not in Allah, when the messenger calleth you to believe in your Lord, and He hath already made a covenant with you, if ye are believers?

(27) And what aileth you that ye spend not in the way of Allah when unto Allah belongeth the inheritance of the heavens and the earth? Those who spent and fought before the victory are not upon a level (with the rest of you). Such are greater in rank than those who spent and fought afterwards. Unto each hath Allah promised good. And Allah is Informed of what ye do.

(28) What aileth you? How foolishly ye judge!

(29) What aileth those who disbelieve, that they keep staring toward thee (O Muhammad), open-eyed,

(30) What aileth you that ye hope not toward Allah for dignity
