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

(61) And of them is he who believeth therein, and of them is he who believeth not therein, and thy Lord is best Aware of the corrupters.

(62) And (O Muhammad) follow that which is inspired in thee, and forbear until Allah give judgment. And He is the best of Judges.

(63) And He it is Who created the heavens and the earth in six Days - and His Throne was upon the water - that He might try you, which of you is best in conduct. Yet if thou (O Muhammad) sayest: Lo! ye will be raised again after death! those who disbelieve will surely say: This is naught but mere magic.

(64) I say not unto you: "I have the treasures of Allah" nor "I have knowledge of the Unseen," nor say I: "Lo! I am an angel!" Nor say I unto those whom your eyes scorn that Allah will not give them good - Allah knoweth best what is in their hearts - Lo! then indeed I should be of the wrong-doers.

(65) We narrate unto thee (Muhammad) the best of narratives in that We have inspired in thee this Qur'an, though aforetime thou wast of the heedless.

(66) And when he provided them with their provision he said: Bring unto me a brother of yours from your father. See ye not that I fill up the measure and I am the best of hosts?

(67) They said: If he stealeth, a brother of his stole before. But Joseph kept it secret in his soul and revealed it not unto them. He said (within himself): Ye are in worse case, and Allah knoweth best (the truth of) that which ye allege.

(68) So, When they despaired of (moving) him, they conferred together apart. The eldest of them said: Know ye not how your father took an undertaking from you in Allah's name and how ye failed in the case of Joseph aforetime? Therefore I shall not go forth from the land until my father giveth leave or Allah judgeth for me. He is the best of Judges.

(69) We sent not before thee (any messengers) save men whom We inspired from among the folk of the townships - Have they not travelled in the land and seen the nature of the consequence for those who were before them? And verily the abode of the Hereafter, for those who ward off (evil), is best. Have ye then no sense? -

(70) Such as persevere in seeking their Lord's Countenance and are regular in prayer and spend of that which We bestow upon them secretly and openly, and overcome evil with good. Theirs will be the sequel of the (heavenly) Home,
