The word(s) "existing" appears 1 time(s) in 1 verse(s) in Quran in Mohsin Khan translation.

(1) Indeed in their stories, there is a lesson for men of understanding. It (the Qur'an) is not a forged statement but a confirmation of (Allah's existing Books) which were before it [i.e. the Taurat (Torah), the Injeel (Gospel) and other Scriptures of Allah] and a detailed explanation of everything and a guide and a Mercy for the people who believe.
