The word(s) "before" appears 356 time(s) in 337 verse(s) in Quran in Mohsin Khan translation.

(261) Have they not travelled in the land and seen what was the end of those who were before them? They were superior to them in strength, and in the traces (which they left) in the land. But Allah seized them with punishment for their sins. And none had they to protect them from Allah.

(262) So be patient (O Muhammad صلى الله عليه وسلم). Verily, the Promise of Allah is true, and ask forgiveness for your fault and glorify the praises of your Lord in the 'Ashi (i.e. the time period after the midnoon till sunset) and in the Ibkar (i.e. the time period from early morning or sunrise till before midnoon) [it is said that, that means the five compulsory congregational Salat (prayers) or the 'Asr and Fajr prayers].

(263) It is He, Who has created you (Adam) from dust, then from a Nutfah [mixed semen drops of male and female sexual discharge (i.e. Adam's offspring)] then from a clot (a piece of coagulated blood), then brings you forth as an infant, then (makes you grow) to reach the age of full strength, and afterwards to be old (men and women)- though some among you die before,- and that you reach an appointed term in order that you may understand.

(264) "Besides Allah"? They will say: "They have vanished from us: Nay, we did not invoke (worship) anything before." Thus Allah leads astray the disbelievers.

(265) And, indeed We have sent Messengers before you (O Muhammad صلى الله عليه وسلم): of some of them We have related to you their story. And of some We have not related to you their story, and it was not given to any Messenger that he should bring a sign except by the Leave of Allah. But, when comes the Commandment of Allah, the matter will be decided with truth, and the followers of falsehood will then be lost.

(266) Have they not travelled through the earth and seen what was the end of those before them? They were more in number than them and mightier in strength, and in the traces (they have left behind them) in the land; yet all that they used to earn availed them not.

(267) When the Messengers came to them, from before them and behind them (saying): "Worship none but Allah", they said: "If our Lord had so willed, He would surely have sent down the angels. So indeed we disbelieve in that with which you have been sent."

(268) And We have assigned for them (devils) intimate companions (in this world), who have made fair-seeming to them, what was before them (evil deeds which they were doing in the present worldly life and disbelief in the Reckoning and the Resurrection) and what was behind them (denial of the matters in the coming life of the Hereafter as regards punishment or reward). And the Word (i.e. the torment) is justified against them as it was justified against those who were among the previous generations of jinn and men that had passed away before them. Indeed they (all) were the losers.

(269) Falsehood cannot come to it from before it or behind it: (it is) sent down by the All-Wise, Worthy of all praise (Allah عز وجل).

(270) Nothing is said to you (O Muhammad صلى الله عليه وسلم) except what was said to the Messengers before you. Verily, your Lord is the Possessor of Forgiveness, and (also) the Possessor of Painful Punishment.
