The word(s) "sake" appears 26 time(s) in 26 verse(s) in Quran in Mohsin Khan translation.

(21) Say (O Muhammad صلى الله عليه وسلم): "Allah Alone I worship by doing religious deeds sincerely for His sake only (and not to show off, and not to set up rivals with Him in worship.)"

(22) So, call you (O Muhammad صلى الله عليه وسلم and the believers) upon (or invoke) Allah making (your) worship pure for Him (Alone) (by worshipping none but Him and by doing religious deeds sincerely for Allah's sake only and not to show off and not to set up rivals with Him in worship), however much the disbelievers (in the Oneness of Allah) may hate (it).

(23) He is the Ever Living, La ilaha illa Huwa (none has the right to be worshipped but He); so invoke Him making your worship pure for Him Alone (by worshipping Him Alone, and none else, and by doing righteous deeds sincerely for Allah's sake only, and not to show off, and not setting up rivals with Him in worship). All the praises and thanks be to Allah, the Lord of the 'Alamin (mankind, jinn and all that exists).

(24) It may be if he divorced you (all) that his Lord will give him instead of you, wives better than you - Muslims (who submit to Allah), believers, obedient (to Allah), turning to Allah in repentance, worshipping Allah sincerely, given to fasting or emigrants (for Allah's sake), previously married and virgins.

(25) And be patient for the sake of your Lord (i.e. perform your duty to Allah)!

(26) Your Lord (O Muhammad صلى الله عليه وسلم) has neither forsaken you nor hates you.
