The word(s) "before" appears 360 time(s) in 348 verse(s) in Quran in Muhammad Habib Shakir translation.

(81) In the manner of the people of Firon and those before them; they disbelieved in Allah's communications, therefore Allah destroyed them on account of their faults; surely Allah is strong, severe in requiting (evil).

(82) In the manner of the people of Firon and those before them; they rejected the communications of their Lord, therefore We destroyed them on account of their faults and We drowned Firon's people, and they were all unjust.

(83) And if they intend to act unfaithfully towards you, so indeed they acted unfaithfully towards Allah before, but He gave (you) mastery over them; and Allah is Knowing, Wise.

(84) And the Jews say: Uzair is the son of Allah; and the Christians say: The Messiah is the son of Allah; these are the words of their mouths; they imitate the saying of those who disbelieved before; may Allah destroy them; how they are turned away!

(85) Certainly they sought (to sow) dissension before, and they meditated plots against you until the truth came, and Allah's commandment prevailed although they were averse (from it).

(86) If good befalls you, it grieves them, and if hardship afflicts you, they say: Indeed we had taken care of our affair before; and they turn back and are glad.

(87) Like those before you; they were stronger than you in power and more abundant in wealth and children, so they enjoyed their portion; thus have you enjoyed your portion as those before you enjoyed their portion; and you entered into vain discourses like the vain discourses in which entered those before you. These are they whose works are null in this world and the hereafter, and these are they who are the losers.

(88) Has not the news of those before them come to them; of the people of Nuh and Ad and Samood, and the people of Ibrahim and the dwellers of Madyan and the overthrown cities; their apostles came to them with clear arguments; so it was not Allah Who should do them injustice, but they were unjust to themselves.

(89) And those who built a masjid to cause harm and for unbelief and to cause disunion among the believers and an ambush to him who made war against Allah and His Apostle before; and they will certainly swear: We did not desire aught but good; and Allah bears witness that they are most surely liars.

(90) And certainly We did destroy generations before you when they were unjust, and their apostles had come to them with clear arguments, and they would not believe; thus do We recompense the guilty people.
