The word(s) "best" appears 257 time(s) in 234 verse(s) in Quran in Abdullah Yusuf Ali translation.

(191) When We bestow favours on man, he turns away, and gets himself remote on his side (instead of coming to Us); and when evil seizes him, (he comes) full of prolonged prayer!

(192) Those who hearken to their Lord, and establish regular Prayer; who (conduct) their affairs by mutual Consultation; who spend out of what We bestow on them for Sustenance;

(193) To Allah belongs the dominion of the heavens and the earth. He creates what He wills (and plans). He bestows (children) male or female according to His Will (and Plan),

(194) Or He bestows both males and females, and He leaves barren whom He will: for He is full of Knowledge and Power.

(195) "Then why are not gold bracelets bestowed on him, or (why) come (not) with him angels accompanying him in procession?"

(196) And they say, "Are our gods best, or he?" This they set forth to thee, only by way of disputation: yea, they are a contentious people.

(197) Or do they say, "He has forged it"? Say: "Had I forged it, then can ye obtain no single (blessing) for me from Allah. He knows best of that whereof ye talk (so glibly)! Enough is He for a witness between me and you! And he is Oft-Forgiving, Most Merciful."

(198) We have enjoined on man kindness to his parents: In pain did his mother bear him, and in pain did she give him birth. The carrying of the (child) to his weaning is (a period of) thirty months. At length, when he reaches the age of full strength and attains forty years, he says, "O my Lord! Grant me that I may be grateful for Thy favour which Thou has bestowed upon me, and upon both my parents, and that I may work righteousness such as Thou mayest approve; and be gracious to me in my issue. Truly have I turned to Thee and truly do I bow (to Thee) in Islam."

(199) Such are they from whom We shall accept the best of their deeds and pass by their ill deeds: (They shall be) among the Companions of the Garden: a promise! of truth, which was made to them (in this life).

(200) But to those who receive Guidance, He increases the (light of) Guidance, and bestows on them their Piety and Restraint (from evil).
