The word(s) "less" appears 175 time(s) in 167 verse(s) in Quran in Muhammad Pickthal translation.

(61) And Moses said: Though ye and all who are in the earth prove thankless, lo! Allah verily is Absolute, Owner of Praise.

(62) Their messengers said unto them: We are but mortals like you, but Allah giveth grace unto whom He will of His slaves. It is not ours to bring you a warrant unless by the permission of Allah. In Allah let believers put their trust!

(63) And those who disbelieved said unto their messengers: Verily we will drive you out from our land, unless ye return to our religion. Then their Lord inspired them, (saying): Verily we shall destroy the wrong-doers,

(64) Hast thou not seen those who gave the grace of Allah in exchange for thanklessness and led their people down to the Abode of Loss,

(65) (Even to) hell? They are exposed thereto. A hapless end!

(66) And lo! in the cattle there is a lesson for you. We give you to drink of that which is in their bellies, from betwixt the refuse and the blood, pure milk palatable to the drinkers.

(67) Such are they whose hearts and ears and eyes Allah hath sealed. And such are the heedless.

(68) Glorified be He Who carried His servant by night from the Inviolable Place of Worship to the Far distant place of worship the neighbourhood whereof We have blessed, that We might show him of Our tokens! Lo! He, only He, is the Hearer, the Seer.

(69) And when harm toucheth you upon the sea, all unto whom ye cry (for succour) fail save Him (alone), but when He bringeth you safe to land, ye turn away, for man was ever thankless.

(70) Or feel ye secure that He will not return you to that (plight) a second time, and send against you a hurricane of wind and drown you for your thanklessness, and then ye will not find therein that ye have any avenger against Us?
