The word(s) "warning" appears 24 time(s) in 24 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) And We send not apostles but as announcers of good news and givers of warning, then whoever believes and acts aright, they shall have no fear, nor shall they grieve.

(2) O assembly of jinn and men! did there not come to you apostles from among you, relating to you My communications and warning you of the meeting of this day of yours? They shall say: We bear witness against ourselves; and this world's life deceived them, and they shall bear witness against their own souls that they were unbelievers.

(3) He sends down the angels with the inspiration by His commandment on whom He pleases of His servants, saying: Give the warning that there is no god but Me, therefore be careful (of your duty) to Me.

(4) And certainly We have repeated (warnings) in this Quran that they may be mindful, but it does not add save to their aversion.

(5) Rightly directing, that he might give warning of severe punishment from Him and give good news to the believers who do good that they shall have a goodly reward,

(6) And We do not send apostles but as givers of good news and warning, and those who disbelieve make a false contention that they may render null thereby the truth, and they take My communications and that with which they are warned for a mockery.

(7) But if they turn back, say: I have given you warning in fairness and I do not know whether what you are threatened with is near or far;

(8) And those who disbelieve shall be driven to hell in companies; until, when they come to it, its doors shall be opened, and the keepers of it shall say to them: Did not there come to you apostles from among you reciting to you the communications of your Lord and warning you of the meeting of this day of yours? They shall say: Yea! But the sentence of punishment was due against the unbelievers.

(9) And thus have We revealed to you an Arabic Quran, that you may warn the mother city and those around it, and that you may give warning of the day of gathering together wherein is no doubt; a party shall be in the garden and (another) party in the burning fire.

(10) Surely We revealed it on a blessed night surely We are ever warning--
