The word(s) "vast" appears 12 time(s) in 12 verse(s) in Quran in Muhammad Pickthal translation.

(1) The likeness of that which they spend in this life of the world is as the likeness of a biting, icy wind which smiteth the harvest of a people who have wronged themselves, and devastateth it. Allah wronged them not, but they do wrong themselves.

(2) It is not (the purpose) of Allah to leave you in your present state till He shall separate the wicked from the good. And it is not (the purpose of) Allah to let you know the Unseen. But Allah chooseth of His messengers whom He will, (to receive knowledge thereof). So believe in Allah and His messengers. If ye believe and ward off (evil), yours will be a vast reward.

(3) Let those fight in the way of Allah who sell the life of this world for the other. Whoso fighteth in the way of Allah, be he slain or be he victorious, on him We shall bestow a vast reward.

(4) 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.

(5) Allah hath given you victory on many fields and on the day of Huneyn, when ye exulted in your multitude but it availed you naught, and the earth, vast as it is, was straitened for you; then ye turned back in flight;

(6) And to the three also (did He turn in mercy) who were left behind, when the earth, vast as it is, was straitened for them, and their own souls were straitened for them till they bethought them that there is no refuge from Allah save toward Him. Then turned He unto them in mercy that they (too) might turn (repentant unto Him). Lo! Allah! He is the Relenting, the Merciful.

(7) Or as darkness on a vast, abysmal sea. There covereth him a wave, above which is a wave, above which is a cloud. Layer upon layer of darkness. When he holdeth out his hand he scarce can see it. And he for whom Allah hath not appointed light, for him there is no light.

(8) Then We inspired Moses, saying: Smite the sea with thy staff. And it parted, and each part was as a mountain vast.

(9) Lo! men who surrender unto Allah, and women who surrender, and men who believe and women who believe, and men who obey and women who obey, and men who speak the truth and women who speak the truth, and men who persevere (in righteousness) and women who persevere, and men who are humble and women who are humble, and men who give alms and women who give alms, and men who fast and women who fast, and men who guard their modesty and women who guard (their modesty), and men who remember Allah much and women who remember - Allah hath prepared for them forgiveness and a vast reward.

(10) We have built the heaven with might, and We it is Who make the vast extent (thereof).
