The word(s) "least" appears 48 time(s) in 47 verse(s) in Quran in Abdullah Yusuf Ali translation.

(41) Whoever works righteousness benefits his own soul; whoever works evil, it is against his own soul: nor is thy Lord ever unjust (in the least) to His Servants.

(42) "If ye believe me not, at least keep yourselves away from me."

(43) Those who reject Allah, hinder (men) from the Path of Allah, and resist the Messenger, after Guidance has been clearly shown to them, will not injure Allah in the least, but He will make their deeds of no effect.

(44) "The Word changes not before Me, and I do not the least injustice to My Servants."

(45) Secret counsels are only (inspired) by the Evil One, in order that he may cause grief to the Believers; but he cannot harm them in the least, except as Allah permits; and on Allah let the Believers put their trust.

(46) Is it that ye are afraid of spending sums in charity before your private consultation (with him)? If, then, ye do not so, and Allah forgives you, then (at least) establish regular prayer; practise regular charity; and obey Allah and His Messenger. And Allah is well-acquainted with all that ye do.

(47) At length, when they see (with their own eyes) that which they are promised,- then will they know who it is that is weakest in (his) helper and least important in point of numbers.
