The word(s) "that" appears 2521 time(s) in 1883 verse(s) in Quran in Mohsin Khan translation.

(1411) Say (O Muhammad صلى الله عليه وسلم): "Do you verily disbelieve in Him Who created the earth in two Days? And you set up rivals (in worship) with Him? that is the Lord of the 'Alamin (mankind, jinn and all that exists).

(1412) When the Messengers came to them, from before them and behind them (saying): "Worship none but Allah", they said: "If our Lord had so willed, He would surely have sent down the angels. So indeed we disbelieve in that with which you have been sent."

(1413) As for 'Ad, they were arrogant in the land without right, and they said: "Who is mightier than us in strength?" See they not that Allah, Who created them was mightier in strength than them. And they used to deny Our Ayat (proofs, evidence, verses, lessons, revelations, etc.)!

(1414) So We sent upon them a furious wind in days of evil omen (for them) that We might give them a taste of disgracing torment in this present worldly life. But surely the torment of the Hereafter will be more disgracing, and they will never be helped.

(1415) And (remember) the Day that the enemies of Allah will be gathered to the Fire, then they will be driven [(to the Fire), former ones being withheld till their later ones will join them].

(1416) And you have not been hiding yourselves (in the world), lest your ears, and your eyes, and your skins should testify against you; but you thought that Allah knew not much of what you were doing.

(1417) And that thought of yours which you thought about your Lord, has brought you to destruction; and you have become (this Day) of those utterly lost!

(1418) 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.

(1419) And those who disbelieve say: "Listen not to this Qur'an, and make noise in the midst of its (recitation) that you may overcome."

(1420) that is the recompense of the enemies of Allah: the Fire. Therein will be for them the eternal home, a (deserving) recompense for that they used to deny Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.).
