The word(s) "awful" appears 87 time(s) in 80 verse(s) in Quran in Muhammad Pickthal translation.

(41) Make not your oaths a deceit between you, lest a foot should slip after being firmly planted and ye should taste evil forasmuch as ye debarred (men) from the way of Allah, and yours should be an awful doom.

(42) Whoso disbelieveth in Allah after his belief - save him who is forced thereto and whose heart is still content with the Faith - but whoso findeth ease in disbelief: On them is wrath from Allah. Theirs will be an awful doom.

(43) So eat of the lawful and good food which Allah hath provided for you, and thank the bounty of your Lord if it is Him ye serve.

(44) And speak not, concerning that which your own tongues qualify (as clean or unclean), the falsehood: "This is lawful, and this is forbidden," so that ye invent a lie against Allah. Lo! those who invent a lie against Allah will not succeed.

(45) Hath your Lord then distinguished you (O men of Makka) by giving you sons, and hath chosen for Himself females from among the angels? Lo! verily ye speak an awful word!

(46) He said: As for him who doeth wrong, we shall punish him, and then he will be brought back unto his Lord, Who will punish him with awful punishment!

(47) The sects among them differ: but woe unto the disbelievers from the meeting of an awful Day.

(48) That (is the command). And whoso magnifieth the sacred things of Allah, it will be well for him in the sight of his Lord. The cattle are lawful unto you save that which hath been told you. So shun the filth of idols, and shun lying speech,

(49) So the (awful) Cry overtook them rightfully, and We made them like as wreckage (that a torrent hurleth). A far removal for wrongdoing folk!

(50) Lo! they who spread the slander are a gang among you. Deem it not a bad thing for you; nay, it is good for you. Unto every man of them (will be paid) that which he hath earned of the sin; and as for him among them who had the greater share therein, his will be an awful doom.
