The word(s) "before" appears 299 time(s) in 289 verse(s) in Quran in Muhammad Pickthal translation.

(151) Never sent We a messenger or a prophet before thee but when He recited (the message) Satan proposed (opposition) in respect of that which he recited thereof. But Allah abolisheth that which Satan proposeth. Then Allah establisheth His revelations. Allah is Knower, Wise;

(152) He knoweth all that is before them and all that is behind them, and unto Allah all things are returned.

(153) And it shall avert the punishment from her if she bear witness before Allah four times that the thing he saith is indeed false,

(154) And verily We have sent down for you revelations that make plain, and the example of those who passed away before you. An admonition unto those who ward off (evil).

(155) Allah hath promised such of you as believe and do good work that He will surely make them to succeed (the present rulers) in the earth even as He caused those who were before them to succeed (others); and that He will surely establish for them their religion which He hath approved for them, and will give them in exchange safety after their fear. They serve Me. They ascribe no thing as partner unto Me. Those who disbelieve henceforth, they are the miscreants.

(156) O ye who believe! Let your slaves, and those of you who have not come to puberty, ask leave of you at three times (before they come into your presence): before the prayer of dawn, and when ye lay aside your raiment for the heat of noon, and after the prayer of night. Three times of privacy for you. It is no sin for them or for you at other times, when some of you go round attendant upon others (if they come into your presence without leave). Thus Allah maketh clear the revelations for you. Allah is Knower, Wise.

(157) And when the children among you come to puberty then let them ask leave even as those before them used to ask it. Thus Allah maketh clear His revelations for you. Allah is Knower, Wise.

(158) We never sent before thee any messengers but lo! they verily ate food and walked in the markets. And We have appointed some of you a test for others: Will ye be steadfast? And thy Lord is ever Seer.

(159) And who spend the night before their Lord, prostrate and standing,

(160) If We will, We can send down on them from the sky a portent so that their necks would remain bowed before it.
