The word(s) "best" appears 144 time(s) in 132 verse(s) in Quran in Muhammad Habib Shakir translation.

(101) Say: Surely my Lord amplifies the means of subsistence for whom He pleases of His servants and straitens (them) for whom (He pleases), and whatever thing you spend, He exceeds it in reward, and He is the best of Sustainers.

(102) What! do you call upon Ba'l and forsake the best of the creators,

(103) And most surely they were with Us, of the elect, the best.

(104) And remember Ismail and Al-Yasha and Zulkifl; and they were all of the best.

(105) Those who listen to the word, then follow the best of it; those are they whom Allah has guided, and those it is who are the men of understanding.

(106) Allah has revealed the best announcement, a book conformable in its various parts, repeating, whereat do shudder the skins of those who fear their Lord, then their skins and their hearts become pliant to the remembrance of Allah; this is Allah's guidance, He guides with it whom He pleases; and (as for) him whom Allah makes err, there is no guide for him.

(107) So that Allah will do away with the worst of what they did and give them their reward for the best of what they do.

(108) And follow the best that has been revealed to you from your Lord before there comes to you the punishment all of a sudden while you do not even perceive;

(109) And every soul shall be paid back fully what it has done, and He knows best what they do.

(110) And not alike are the good and the evil. Repel (evil) with what is best, when lo! he between whom and you was enmity would be as if he were a warm friend.
