The word(s) "severe" appears 71 time(s) in 70 verse(s) in Quran in Mohsin Khan translation.

(51) Verily, those who turn away from Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc. by attacking, distorting and denying them) are not hidden from Us. Is he who is cast into the Fire better or he who comes secure on the Day of Resurrection? Do what you will. Verily He is All-Seer of what you do (this is a severe threat to the disbelievers ).

(52) And truly, if We give him a taste of mercy from Us, after some adversity (severe poverty or disease, etc.) has touched him, he is sure to say: "This is due to my (merit); I think not that the Hour will be established. But if I am brought back to my Lord, surely, there will be for me the best (wealth) with Him. Then, We verily, will show to the disbelievers what they have done, and We shall make them taste a severe torment.

(53) And those who dispute concerning Allah (His religion of Islamic Monotheism with which Muhammad صلى الله عليه و سلم has been sent), after it has been accepted (by the people), of no use is their dispute before their Lord and on them is wrath, and for them will be a severe torment.

(54) And He answers (the invocation of) those who believe (in the Oneness of Allah - Islamic Monotheism) and do righteous good deeds, and gives them increase of His Bounty. And as for the disbelievers, theirs will be a severe torment.

(55) This (Qur'an) is a guidance. And those who disbelieve in the Ayat (proofs, evidence, verses, lessons, signs, revelations) of their Lord, for them there is a painful torment of Rijz (a severe kind of punishment).

(56) Muhammad (صلى الله عليه وسلم) is the Messenger of Allah. And those who are with him are severe against disbelievers, and merciful among themselves. You see them bowing and falling down prostrate (in prayer), seeking Bounty from Allah and (His) Good Pleasure. The mark of them (i.e. of their Faith) is on their faces (foreheads) from the traces of prostration (during prayers). This is their description in the Taurat (Torah). But their description in the Injeel (Gospel) is like a (sown) seed which sends forth its shoot, then makes it strong, and becomes thick and it stands straight on its stem, delighting the sowers, that He may enrage the disbelievers with them. Allah has promised those among them who believe (i.e. all those who follow Islamic Monotheism, the religion of Prophet Muhammad صلى الله عليه وسلم till the Day of Resurrection) and do righteous good deeds, forgiveness and a mighty reward (i.e. Paradise).

(57) "Who set up another ilah (god) with Allah. Then both of you cast him in the severe torment."

(58) Know that the life of this world is only play and amusement, pomp and mutual boasting among you, and rivalry in respect of wealth and children. (It is) as the likeness of vegetation after rain, thereof the growth is pleasing to the tiller; afterwards it dries up and you see it turning yellow; then it becomes straw. But in the Hereafter (there is) a severe torment (for the disbelievers - evil-doers), and (there is) Forgiveness from Allah and (His) Good Pleasure (for the believers - good-doers). And the life of this world is only a deceiving enjoyment.

(59) Allah has prepared for them a severe torment. Evil indeed is that which they used to do.

(60) That is because they opposed Allah and His Messenger (Muhammad صلى الله عليه وسلم). And whosoever opposes Allah, then verily, Allah is severe in punishment.
