The word(s) "eternal" appears 7 time(s) in 7 verse(s) in Quran in Mohsin Khan translation.

(1) Say: "Shall I inform you of things far better than those? For Al-Muttaqun (the pious - See V.2:2) there are Gardens (Paradise) with their Lord, underneath which rivers flow. Therein (is their) eternal (home) and Azwajun Mutahharatun (purified mates or wives). And Allah will be pleased with them. And Allah is All-Seer of the (His) slaves".

(2) And what think those who invent a lie against Allah, on the Day of Resurrection? [i.e. Do they think that they will be forgiven and excused! Nay, they will have an eternal punishment in the Fire of Hell]. Truly, Allah is full of Bounty to mankind, but most of them are ungrateful.

(3) The description of the Paradise which the Muttaqun (the pious - See V.2:2) have been promised: Underneath it rivers flow, its provision is eternal and so is its shade; this is the end (final destination) of the Muttaqun (the pious - See V.2:2), and the end (final destination) of the disbelievers is Fire. (See Verse 47:15)

(4) And this life of the world is only an amusement and a play! Verily, the home of the Hereafter - that is the life indeed (i.e. the eternal life that will never end), if they but knew .

(5) 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.).

(6) "Enter you therein in peace and security - this is a Day of eternal life!"

(7) So it tasted the evil result of its affair (disbelief), and the consequence of its affair (disbelief) was loss (destruction in this life and an eternal punishment in the Hereafter).
