The word(s) "painful" appears 73 time(s) in 73 verse(s) in Quran in Muhammad Pickthal translation.

(51) Or have they partners (of Allah) who have made lawful for them in religion that which Allah allowed not? And but for a decisive word (gone forth already), it would have been judged between them. Lo! for wrong-doers is a painful doom.

(52) The way (of blame) is only against those who oppress mankind, and wrongfully rebel in the earth. For such there is a painful doom.

(53) But the factions among them differed. Then woe unto those who do wrong from the doom of a painful day.

(54) That will envelop the people. This will be a painful torment.

(55) Who heareth the revelations of Allah recited unto him, and then continueth in pride as though he heard them not. Give him tidings of a painful doom.

(56) This is guidance. And those who disbelieve the revelations of their Lord, for them there is a painful doom of wrath.

(57) Then, when they beheld it as a dense cloud coming toward their valleys, they said: Here is a cloud bringing us rain. Nay, but it is that which ye did seek to hasten, a wind wherein is painful torment,

(58) O our people! respond to Allah's summoner and believe in Him. He will forgive you some of your sins and guard you from a painful doom.

(59) Say unto those of the wandering Arabs who were left behind: Ye will be called against a folk of mighty prowess, to fight them until they surrender; and if ye obey, Allah will give you a fair reward; but if ye turn away as ye did turn away before, He will punish you with a painful doom.

(60) There is no blame for the blind, nor is there blame for the lame, nor is there blame for the sick (that they go not forth to war). And whoso obeyeth Allah and His messenger, He will make him enter Gardens underneath which rivers flow; and whoso turneth back, him will He punish with a painful doom.
