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

(91) He said: My Lord! because Thou hast bestowed a favor on me, I shall never be a backer of the guilty.

(92) Said one of them: O my father! employ him, surely the best of those that you can employ is the strong man, the faithful one.

(93) And Musa said: My Lord knows best who comes with guidance from Him, and whose shall be the good end of the abode; surely the unjust shall not be successful.

(94) Surely you cannot guide whom you love, but Allah guides whom He pleases, and He knows best the followers of the right way.

(95) Most surely He Who has made the Quran binding on you will bring you back to the destination. Say: My Lord knows best him who has brought the guidance and him who is in manifest error.

(96) And (as for) those who believe and do good, We will most certainly do away with their evil deeds and We will most certainly reward them the best of what they did.

(97) And among men is he who says: We believe in Allah; but when he is persecuted in (the way of) Allah he thinks the persecution of men to be as the chastisement of Allah; and if there come assistance from your Lord, they would most certainly say: Surely we were with you. What! is not Allah the best knower of what is in the breasts of mankind.

(98) And (We sent) Ibrahim, when he said to his people: Serve Allah and be careful of (your duty to) Him; this is best for you, if you did but know:

(99) And do not dispute with the followers of the Book except by what is best, except those of them who act unjustly, and say: We believe in that which has been revealed to us and revealed to you, and our Allah and your Allah is One, and to Him do we submit.

(100) Then give to the near of kin his due, and to the needy and the wayfarer; this is best for those who desire Allah's pleasure, and these it is who are successful.
