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

(31) Those of the believers who sit still, other than those who have a (disabling) hurt, are not on an equality with those who strive in the way of Allah with their wealth and lives. Allah hath conferred on those who strive with their wealth and lives a rank above the sedentary. Unto each Allah hath promised good, but He hath bestowed on those who strive a great reward above the sedentary;

(32) There is no good in much of their secret conferences save (in) him who enjoineth almsgiving and kindness and peace-making among the people. Whoso doeth that, seeking the good pleasure of Allah, We shall bestow on him a vast reward.

(33) Save those who repent and amend and hold fast to Allah and make their religion pure for Allah (only). Those are with the believers. And Allah will bestow on the believers an immense reward.

(34) The people of the Scripture ask of thee that thou shouldst cause an (actual) Book to descend upon them from heaven. They asked a greater thing of Moses aforetime, for they said: Show us Allah plainly. The storm of lightning seized them for their wickedness. Then (even) after that) they chose the calf (for worship) after clear proofs (of Allah's Sovereignty) had come unto them. And We forgave them that! And We bestowed on Moses evident authority.

(35) But those of them who are firm in knowledge and the believers believe in that which is revealed unto thee, and that which was revealed before thee, especially the diligent in prayer and those who pay the poor-due, the believers in Allah and the Last Day. Upon these We shall bestow immense reward.

(36) And We caused Jesus, son of Mary, to follow in their footsteps, confirming that which was (revealed) before him in the Torah, and We bestowed on him the Gospel wherein is guidance and a light, confirming that which was (revealed) before it in the Torah - a guidance and an admonition unto those who ward off (evil).

(37) When they come unto you (Muslims), they say: We believe; but they came in unbelief and they went out in the same; and Allah knoweth best what they were hiding.

(38) The Jews say: Allah's hand is fettered. Their hands are fettered and they are accursed for saying so. Nay, but both His hands are spread out wide in bounty. He bestoweth as He will. That which hath been revealed unto thee from thy Lord is certain to increase the contumacy and disbelief of many of them, and We have cast among them enmity and hatred till the Day of Resurrection. As often as they light a fire for war, Allah extinguisheth it. Their effort is for corruption in the land, and Allah loveth not corrupters.

(39) Eat of that which Allah hath bestowed on you as food lawful and good, and keep your duty to Allah in Whom ye are believers.

(40) Jesus, son of Mary, said: O Allah, Lord of us! Send down for us a table spread with food from heaven, that it may be a feast for us, for the first of us and for the last of us, and a sign from Thee. Give us sustenance, for Thou art the best of Sustainers.
