The word(s) "best" appears 173 time(s) in 159 verse(s) in Quran in Muhammad Pickthal translation.

(121) And We bestowed on him Isaac and Jacob, and We established the prophethood and the Scripture among his seed, and We gave him his reward in the world, and lo! in the Hereafter he verily is among the righteous.

(122) He said: Lo! Lot is there. They said: We are best aware of who is there. We are to deliver him and his household, all save his wife, who is of those who stay behind.

(123) He coineth for you a similitude of yourselves. Have ye, from among those whom your right hands possess, partners in the wealth We have bestowed upon you, equal with you in respect thereof, so that ye fear them as ye fear each other (that ye ascribe unto Us partners out of that which We created)? Thus We display the revelations for people who have sense.

(124) So give to the kinsman his due, and to the needy, and to the wayfarer. That is best for those who seek Allah's Countenance. And such are they who are successful.

(125) Who forsake their beds to cry unto their Lord in fear and hope, and spend of that We have bestowed on them.

(126) Say: Lo! my Lord enlargeth the provision for whom He will of His bondmen, and narroweth (it) for him. And whatsoever ye spend (for good) He replaceth it. And He is the best of Providers.

(127) Those before them denied, and these have not attained a tithe of that which We bestowed on them (of old); yet they denied My messengers. How intense then was My abhorrence (of them)!

(128) Lo! those who read the Scripture of Allah, and establish worship, and spend of that which We have bestowed on them secretly and openly, they look forward to imperishable gain,

(129) Will ye cry unto Baal and forsake the best of creators,

(130) Or are theirs the treasures of the mercy of thy Lord, the Mighty, the bestower?
