The word(s) "painful" appears 72 time(s) in 72 verse(s) in Quran in Muhammad Habib Shakir translation.

(61) There is no harm in the blind, nor is there any harm in the lame, nor is there any harm in the sick (if they do not go forth); and whoever obeys Allah and His Apostle, He will cause him to enter gardens beneath which rivers flow, and whoever turns back, He will punish him with a painful punishment.

(62) It is they who disbelieved and turned you away from the Sacred Mosque and (turned off) the offering withheld from arriving at its destined place; and were it not for the believing men and the believing women, whom, not having known, you might have trodden down, and thus something hateful might have afflicted you on their account without knowledge-- so that Allah may cause to enter into His mercy whomsoever He pleases; had they been widely separated one from another, We would surely have punished those who disbelieved from among them with a painful punishment.

(63) And We left therein a sign for those who fear the painful punishment.

(65) Like those before them shortly; they tasted the evil result of their affair, and they shall have a painful punishment.

(66) O you who believe! shall I lead you to a merchandise which may deliver you from a painful chastisement?

(67) Has there not come to you the story of those who disbelieved before, then tasted the evil result of their conduct, and they had a painful punishment?

(68) Say: Have you considered if Allah should destroy me and those with me-- rather He will have mercy on us; yet who will protect the unbelievers from a painful punishment?

(69) Surely We sent Nuh to his people, saying: Warn your people before there come upon them a painful chastisement.

(70) And food that chokes and a painful punishment,
