The word(s) "then" appears 1110 time(s) in 997 verse(s) in Quran in Mohsin Khan translation.

(281) Say: "Is there of your (Allah's so-called) partners one that guides to the truth?" Say: "It is Allah Who guides to the truth. Is then He Who guides to the truth more worthy to be followed, or he who finds not guidance (himself) unless he is guided? then, what is the matter with you? How judge you?"

(282) Or do they say: "He (Muhammad صلى الله عليه وسلم) has forged it?" Say: "Bring then a Surah (chapter) like unto it, and call upon whomsoever you can besides Allah, if you are truthful!"

(283) Nay, they have belied the knowledge whereof they could not comprehend and what has not yet been fulfilled (i.e. their punishment). Thus those before them did belie. then see what was the end of the Zalimun (polytheists and wrong-doers)!

(284) Is it then that when it has actually befallen, you will believe in it? What! Now (you believe)? And you used (aforetime) to hasten it on!"

(285) then it will be said to them who wronged themselves: "Taste you the everlasting torment! Are you recompensed (aught) save what you used to earn?"

(286) (A brief) enjoyment in this world! - and then unto Us will be their return, then We shall make them taste the severest torment because they used to disbelieve [in Allah, belie His Messengers, deny and challenge His Ayat (proofs, signs, verses, etc.)].

(287) And recite to them the news of Nuh (Noah). When he said to his people: "O my people, if my stay (with you), and my reminding (you) of the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah is hard on you, then I put my trust in Allah. So devise your plot, you and your partners, and let not your plot be in doubt for you. then pass your sentence on me and give me no respite.

(288) "But if you turn away [from accepting my doctrine of Islamic Monotheism, i.e. to worship none but Allah], then no reward have I asked of you; my reward is only from Allah, and I have been commanded to be of the Muslims (i.e. those who submit to Allah's Will)."

(289) They denied him, but We delivered him, and those with him in the ship, and We made them generations replacing one after another, while We drowned those who belied Our Ayat (proofs, evidence, lessons, signs, revelations, etc.). then see what was the end of those who were warned.

(290) then after him We sent Messengers to their people. They brought them clear proofs, but they would not believe what they had already rejected beforehand. Thus We seal the hearts of the transgressors (those who disbelieve in the Oneness of Allah and disobey Him).
