The word(s) "before" appears 327 time(s) in 315 verse(s) in Quran in Saheeh International translation.

(1) And who believe in what has been revealed to you, [O Muhammad], and what was revealed before you, and of the Hereafter they are certain [in faith].

(2) O mankind, worship your Lord, who created you and those before you, that you may become righteous -

(3) And give good tidings to those who believe and do righteous deeds that they will have gardens [in Paradise] beneath which rivers flow. Whenever they are provided with a provision of fruit therefrom, they will say, "This is what we were provided with before." And it is given to them in likeness. And they will have therein purified spouses, and they will abide therein eternally.

(4) And [mention] when We said to the angels, "Prostrate before Adam"; so they prostrated, except for Iblees. He refused and was arrogant and became of the disbelievers.

(5) Indeed, those who believed and those who were Jews or Christians or Sabeans [before Prophet Muhammad] - those [among them] who believed in Allah and the Last Day and did righteousness - will have their reward with their Lord, and no fear will there be concerning them, nor will they grieve.

(6) And when they meet those who believe, they say, "We have believed"; but when they are alone with one another, they say, "Do you talk to them about what Allah has revealed to you so they can argue with you about it before your Lord?" Then will you not reason?

(7) And when there came to them a Book from Allah confirming that which was with them - although before they used to pray for victory against those who disbelieved - but [then] when there came to them that which they recognized, they disbelieved in it; so the curse of Allah will be upon the disbelievers.

(8) And when it is said to them, "Believe in what Allah has revealed," they say, "We believe [only] in what was revealed to us." And they disbelieve in what came after it, while it is the truth confirming that which is with them. Say, "Then why did you kill the prophets of Allah before, if you are [indeed] believers?"

(9) Say, "Whoever is an enemy to Gabriel - it is [none but] he who has brought the Qur'an down upon your heart, [O Muhammad], by permission of Allah, confirming that which was before it and as guidance and good tidings for the believers."

(10) Or do you intend to ask your Messenger as Moses was asked before? And whoever exchanges faith for disbelief has certainly strayed from the soundness of the way.
