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

(531) See you not that Allah drives the clouds gently, then joins them together, then makes them into a heap of layers, and you see the rain comes forth from between them; and He sends down from the sky hail (like) mountains, (or there are in the heaven mountains of hail from where He sends down hail), and strikes therewith whom He wills, and averts it from whom He wills. The vivid flash of its (clouds) lightning nearly blinds the sight. [Tafsir At-Tabari].

(532) They (hypocrites) say: "We have believed in Allah and in the Messenger (Muhammad صلى الله عليه وسلم), and we obey," then a party of them turn away thereafter, such are not believers.

(533) And when the children among you come to puberty, then let them (also) ask for permission, as those senior to them (in age). Thus Allah makes clear His Ayat (Commandments and legal obligations) for you. And Allah is All-Knowing, All-Wise.

(534) Certainly, to Allah belongs all that is in the heavens and the earth. Surely, He knows your condition and (He knows) the Day when they will be brought back to Him, then He will inform them of what they did. And Allah is All-Knower of everything.

(535) Thus they (false gods - all deities other than Allah) will belie you (polytheists) regarding what you say (that they are gods besides Allah): then you can neither avert (the punishment), nor get help. And whoever among you does wrong (i.e. sets up rivals to Allah), We shall make him taste a great torment.

(536) And those who disbelieve say: "Why is not the Qur'an revealed to him all at once?" Thus (it is sent down in parts), that We may strengthen your heart thereby. And We have revealed it to you gradually, in stages. (It was revealed to the Prophet صلى الله عليه وسلم in 23 years.).

(537) And We said: "Go you both to the people who have denied Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.)." then We destroyed them with utter destruction.

(538) And indeed they have passed by the town [of Prophet Lut (Lot)] on which was rained the evil rain. Did they (disbelievers) not then see it (with their own eyes)? Nay! But they used not to expect any resurrection.

(539) Have you (O Muhammad صلى الله عليه وسلم) seen him who has taken as his ilah (god) his own vain desire? Would you then be a Wakil (a disposer of his affairs or a watcher) over him?

(540) Have you not seen how your Lord spread the shadow. If He willed, He could have made it still - But We have made the sun its guide (i.e. after the sunrise, the shadow shrinks and vanishes at midnoon and then again appears in the afternoon with the decline of the sun, and had there been no sunlight, there would have been no shadow).
