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

(181) Never did We send a Messenger or a Prophet before you but when he did recite the revelation or narrated or spoke, Shaitan (Satan) threw (some falsehood) in it. But Allah abolishes that which Shaitan (Satan) throws in. Then Allah establishes His Revelations. And Allah is All-Knower, All-Wise:

(182) He knows what is before them, and what is behind them. And to Allah return all matters (for decision).

(183) And strive hard in Allah's Cause as you ought to strive (with sincerity and with all your efforts that His Name should be superior). He has chosen you (to convey His Message of Islamic Monotheism to mankind by inviting them to His religion of Islam), and has not laid upon you in religion any hardship: it is the religion of your father Ibrahim (Abraham) (Islamic Monotheism). It is He (Allah) Who has named you Muslims both before and in this (the Qur'an), that the Messenger (Muhammad صلى الله عليه وسلم) may be a witness over you and you be witnesses over mankind! So perform As-Salat (Iqamat-as-Salat), give Zakat and hold fast to Allah [i.e. have confidence in Allah, and depend upon Him in all your affairs]. He is your Maula (Patron, Lord), what an Excellent Maula (Patron, Lord) and what an Excellent Helper!

(184) "Verily, this we have been promised - we and our fathers before (us)! This is only the tales of the ancients!"

(185) And indeed We have sent down for you Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) that make things plain, and the example of those who passed away before you, and an admonition for those who are Al-Muttaqun (the pious - See V.2:2).

(186) Allah has promised those among you who believe and do righteous good deeds, that He will certainly grant them succession to (the present rulers) in the land, as He granted it to those before them, and that He will grant them the authority to practise their religion which He has chosen for them (i.e. Islam). And He will surely give them in exchange a safe security after their fear (provided) they (believers) worship Me and do not associate anything (in worship) with Me. But whoever disbelieves after this, they are the Fasiqun (rebellious, disobedient to Allah).

(187) O you who believe! Let your slaves and slave-girls, and those among you who have not come to the age of puberty ask your permission (before they come to your presence) on three occasions: before Fajr (morning) Salat (prayer), and while you put off your clothes for the noonday (rest), and after the 'Isha' (late-night) Salat (prayer). (These) three times are of privacy for you; other than these times there is no sin on you or on them to move about, attending to each other. Thus Allah makes clear the Ayat (the Verses of this Qur'an, showing proofs for the legal aspects of permission for visits) to you. And Allah is All-Knowing, All-Wise.

(188) And We never sent before you (O Muhammad صلى الله عليه وسلم) any of the Messengers but verily, they ate food and walked in the markets. And We have made some of you as a trial for others: will you have patience? And your Lord is Ever All-Seer (of everything).

(189) And it is He Who sends the winds as heralds of glad tidings, going before His Mercy (rain); and We send down pure water from the sky.

(190) [Fir'aun (Pharaoh)] said: "You have believed in him before I give you leave. Surely, he indeed is your chief, who has taught you magic! So verily, you shall come to know. Verily, I will cut off your hands and your feet on opposite sides, and I will crucify you all."
