The word(s) "best" appears 206 time(s) in 195 verse(s) in Quran in Mohsin Khan translation.

(151) And they are with Us, verily, of the chosen and the best!

(152) And remember Isma'il (Ishmael), Alyasa' (Elisha), and Dhul-Kifl (Isaiah), all are among the best.

(153) And when some hurt touches man, he cries to his Lord (Allah Alone), turning to Him in repentance. But when He bestows a favour upon him from Himself, he forgets that for which he cried for before, and he sets up rivals to Allah, in order to mislead others from His Path. Say: "Take pleasure in your disbelief for a while: surely you are (one) of the dwellers of the Fire!"

(154) Those who listen to the Word [good advice La ilaha illallah - (none has the right to be worshipped but Allah) and Islamic Monotheism] and follow the best thereof (i.e. worship Allah Alone, repent to Him and avoid Taghut) those are (the ones) whom Allah has guided and those are men of understanding.

(155) Allah has sent down the best Statement, a Book (this Qur'an), its parts resembling each other (in goodness and truth) (and) oft-repeated. The skins of those who fear their Lord shiver from it (when they recite it or hear it). Then their skin and their heart soften to the remembrance of Allah. That is the guidance of Allah. He Guides therewith whom He wills; and whomever Allah sends astray, for him there is no guide.

(156) So that Allah may expiate from them the evil of what they did and give them the reward, according to the best of what they used to do.

(157) "And follow the best of that which is sent down to you from your Lord (i.e. this Qur'an, do what it orders you to do and keep away from what it forbids), before the torment comes on you suddenly while you perceive not!"

(158) And each person will be paid in full of what he did; and He is best Aware of what they do.

(159) The Forgiver of sin, the Acceptor of repentance, the Severe in punishment, the bestower (of favours). La ilaha illa Huwa (none has the right to be worshipped but He), to Him is the final return.

(160) Verily those who dispute about the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah, without any authority having come to them, there is nothing else in their breasts except pride [to accept you (Muhammad صلى الله عليه وسلم) as a Messenger of Allah and to obey you] . They will never have it (i.e. Prophethood which Allah has bestowed upon you). So seek refuge in Allah (O Muhammad صلى الله عليه وسلم from the arrogants). Verily, it is He Who is the All-Hearer, the All-Seer.
