The word(s) "lean" appears 18 time(s) in 15 verse(s) in Quran in Mohsin Khan translation.

(11) He said: "This is my stick, whereon I lean, and wherewith I beat down branches for my sheep, and wherein I find other uses."

(12) And proclaim to mankind the Hajj (pilgrimage). They will come to you on foot and on every lean camel, they will come from every deep and distant (wide) mountain highway (to perform Hajj ).

(13) In houses (mosques) which Allah has ordered to be raised (to be cleaned, and to be honoured), in them His Name is remembered [i.e. Adhan, Iqamah, Salat (prayers), invocations, recitation of the Qur'an etc.]. Therein glorify Him (Allah) in the mornings and in the afternoons or the evenings,

(14) Except him who brings to Allah a clean heart [clean from Shirk (polytheism) and Nifaq (hypocrisy)]."

(15) There was no other answer given by his people except that they said: "Drive out the family of Lut (Lot) from your city Verily, these are men who want to be clean and pure!"
