The word(s) "denial" appears 9 time(s) in 9 verse(s) in Quran in Mohsin Khan translation.

(1) 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).

(2) And when Our Clear Verses are recited to them, you will notice a denial on the faces of the disbelievers! They are nearly ready to attack with violence those who recite Our Verses to them. Say: "Shall I tell you of something worse than that? The Fire (of Hell) which Allah has promised to those who disbelieved, and worst indeed is that destination!"

(3) Thus have We caused it (the denial of the Qur'an) to enter the hearts of the Mujrimun (criminals, polytheists, sinners).

(4) And those before them belied; these have not received even a tenth of what We had granted to those (of old); yet they belied My Messengers. Then how (terrible) was My denial (punishment)!

(5) Then I took hold of those who disbelieved: and how terrible was My denial (punishment)!

(6) And We have assigned for them (devils) intimate companions (in this world), who have made fair-seeming to them, what was before them (evil deeds which they were doing in the present worldly life and disbelief in the Reckoning and the Resurrection) and what was behind them (denial of the matters in the coming life of the Hereafter as regards punishment or reward). And the Word (i.e. the torment) is justified against them as it was justified against those who were among the previous generations of jinn and men that had passed away before them. Indeed they (all) were the losers.

(7) And there can be no denial of its befalling.

(8) And indeed those before them belied (the Messengers of Allah), then how terrible was My denial (punishment)?

(9) Verily, it (Hell, or their denial of Prophet Muhammad صلى الله عليه وسلم, or the Day of Resurrection) is but one of the greatest (signs).
