The word(s) "ill" appears 2805 time(s) in 1953 verse(s) in Quran in Mohsin Khan translation.

(311) And the life of this world is nothing but play and amusement. But far better is the house in the Hereafter for those who are Al-Muttaqun (the pious - See V.2:2). Will you not then understand?

(312) Verily, (many) Messengers were denied before you (O Muhammad صلى الله عليه وسلم), but with patience they bore the denial, and they were hurt; till Our Help reached them, and none can alter the Words (Decisions) of Allah. Surely there has reached you the information (news) about the Messengers (before you).

(313) If their aversion (from you, O Muhammad صلى الله عليه وسلم and from that with which you have been sent) is hard on you, (and you cannot be patient of their harm to you), then if you were able to seek a tunnel in the earth or a ladder to the sky, so that you may bring them a sign (and you cannot do it, so be patient). And had Allah willed, He could have gathered them together (all) on true guidance, so be not you one of those who are Al-Jahilun (the ignorant).

(314) It is only those who listen (to the Message of Prophet Muhammad صلى الله عليه وسلم), will respond (benefit from it), but as for the dead (i.e. disbelievers), Allah will raise them up, then to Him they will be returned (for their recompense).

(315) Those who reject Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) are deaf and dumb in the darkness. Allah sends astray whom He wills and He guides on the Straight Path whom He wills.

(316) Nay! To Him Alone you would call, and, if He wills, He would remove that (distress) for which you call upon Him, and you would forget at that time whatever partners you joined (with Him in worship)!

(317) Say: "Tell me, if the punishment of Allah comes to you suddenly (during the night), or openly (during the day), will any be destroyed except the Zalimun (polytheists and wrong-doing people)?"

(318) But those who reject Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), the torment will touch them for their disbelief (and for their belying the Message of Muhammad صلى الله عليه وسلم). [Tafsir Al-Qurtubi].

(319) Say (O Muhammad صلى الله عليه وسلم): "I don't tell you that with me are the treasures of Allah, nor (that) I know the Unseen; nor I tell you that I am an angel. I but follow what is revealed to me." Say: "Are the blind and the one who sees equal? Will you not then take thought?"

(320) And warn therewith (the Qur'an) those who fear that they will be gathered before their Lord, when there will be neither a protector nor an intercessor for them besides Him, so that they may fear Allah and keep their duty to Him (by abstaining from committing sins and by doing all kinds of good deeds which He has ordained).
