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

(51) O Children of Adam! We have revealed unto you raiment to conceal your shame, and splendid vesture, but the raiment of restraint from evil, that is best. This is of the revelations of Allah, that they may remember.

(52) And if there is a party of you which believeth in that wherewith I have been sent, and there is a party which believeth not, then have patience until Allah judge between us. He is the best of all who deal in judgment.

(53) We should have invented a lie against Allah if we returned to your religion after Allah hath rescued us from it. It is not for us to return to it unless Allah our Lord should (so) will. Our Lord comprehendeth all things in knowledge. In Allah do we put our trust. Our Lord! Decide with truth between us and our folk, for Thou art the best of those who make decision.

(54) And Moses chose of his people seventy men for Our appointed tryst and, when the trembling came on them, he said: My Lord! If Thou hadst willed Thou hadst destroyed them long before, and me with them. Wilt thou destroy us for that which the ignorant among us did? It is but Thy trial (of us). Thou sendest whom Thou wilt astray and guidest whom Thou wilt: Thou art our Protecting Friend, therefore forgive us and have mercy on us, Thou, the best of all who show forgiveness.

(55) Who establish worship and spend of that We have bestowed on them.

(56) And when those who disbelieve plot against thee (O Muhammad) to wound thee fatally, or to kill thee or to drive thee forth; they plot, but Allah (also) plotteth; and Allah is the best of plotters.

(57) That is because Allah never changeth the grace He hath bestowed on any people until they first change that which is in their hearts, and (that is) because Allah is Hearer, Knower.

(58) Go forth, light-armed and heavy-armed, and strive with your wealth and your lives in the way of Allah! That is best for you if ye but knew.

(59) Nor spend they any spending, small or great, nor do they cross a valley, but it is recorded for them, that Allah may repay them the best of what they used to do.

(60) For those who do good is the best (reward) and more (thereto). Neither dust nor ignominy cometh near their faces. Such are rightful owners of the Garden; they will abide therein.
