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

(181) And if they reject you, then already before you did the people of Nuh and Ad and Samood reject (prophets).

(182) And We did not send before you any apostle or prophet, but when he desired, the Shaitan made a suggestion respecting his desire; but Allah annuls that which the Shaitan casts, then does Allah establish His communications, and Allah is Knowing, Wise,

(183) And that those who have been given the knowledge may know that it is the truth from your Lord, so they may believe in it and their hearts may be lowly before it; and most surely Allah is the Guide of those who believe into a right path.

(184) He knows what is before them and what is behind them and to Allah are all affairs turned back.

(185) And strive hard in (the way of) Allah, (such) a striving as is due to Him; He has chosen you and has not laid upon you an hardship in religion; the faith of your father Ibrahim; He named you Muslims before and in this, that the Apostle may be a bearer of witness to you, and you may be bearers of witness to the people; therefore keep up prayer and pay the poor-rate and hold fast by Allah; He is your Guardian; how excellent the Guardian and how excellent the Helper!

(186) Except before their mates or those whom their right hands possess, for they surely are not blameable,

(187) So We revealed to him, saying: Make the ark before Our eyes and (according to) Our revelation; and when Our command is given and the valley overflows, take into it of every kind a pair, two, and your followers, except those among them against whom the word has gone forth, and do not speak to Me in respect of those who are unjust; surely they shall be drowned.

(188) Haply I may do good in that which I have left. By no means! it is a (mere) word that he speaks; and before them is a barrier until the day they are raised.

(189) Why did they not bring four witnesses of it? But as they have not brought witnesses they are liars before Allah.

(190) And certainly We have sent to you clear communications and a description of those who have passed away before you, and an admonition to those who guard (against evil).
