The word(s) "inside" appears 3 time(s) in 3 verse(s) in Quran in Mohsin Khan translation.

(1) Allah has not made for any man two hearts inside his body. Neither has He made your wives whom you declare to be like your mothers' backs, your real mothers. [az-Zihar is the saying of a husband to his wife, "You are to me like the back of my mother" i.e. You are unlawful for me to approach], nor has He made your adopted sons your real sons. That is but your saying with your mouths. But Allah says the truth, and He guides to the (Right) Way.

(2) He would have indeed remained inside its belly (the fish) till the Day of Resurrection.

(3) On the Day when the hypocrites - men and women - will say to the believers: "Wait for us! Let us get something from your light!" It will be said: "Go back to your rear! Then seek a light!" So a wall will be put up between them, with a gate therein. inside it will be mercy, and outside it will be torment."
