The word(s) "thou" appears 996 time(s) in 764 verse(s) in Quran in Abdullah Yusuf Ali translation.

(271) If thou dost marvel (at their want of faith), strange is their saying: "When we are (actually) dust, shall we indeed then be in a creation renewed?" They are those who deny their Lord! They are those round whose necks will be yokes (of servitude): they will be Companions of the Fire, to dwell therein (for aye)!

(272) And the Unbelievers say: "Why is not a sign sent down to him from his Lord?" But thou art truly a warner, and to every people a guide.

(273) For Him (alone) is prayer in Truth: any others that they call upon besides Him hear them no more than if they were to stretch forth their hands for water to reach their mouths but it reaches them not: for the prayer of those without Faith is nothing but (futile) wandering (in the mind).

(274) "Those who believe, and whose hearts find satisfaction in the remembrance of Allah: for without doubt in the remembrance of Allah do hearts find satisfaction.

(275) Thus have we sent thee amongst a People before whom (long since) have (other) Peoples (gone and) passed away; in order that thou mightest rehearse unto them what We send down unto thee by inspiration; yet do they reject (Him), the Most Gracious! Say: "He is my Lord! There is no god but He! On Him is my trust, and to Him do I turn!"

(276) Thus have We revealed it to be a judgment of authority in Arabic. Wert thou to follow their (vain) desires after the knowledge which hath reached thee, then wouldst thou find neither protector nor defender against Allah.

(277) The Unbelievers say: "No messenger art thou." Say: "Enough for a witness between me and you is Allah, and such as have knowledge of the Book."

(278) A. L. R. A Book which We have revealed unto thee, in order that thou mightest lead mankind out of the depths of darkness into light - by the leave of their Lord - to the Way of (Him) the Exalted in power, worthy of all praise!-

(279) Seest thou not that Allah created the heavens and the earth in Truth? If He so will, He can remove you and put (in your place) a new creation?

(280) Seest thou not how Allah sets forth a parable? - A goodly word like a goodly tree, whose root is firmly fixed, and its branches (reach) to the heavens,- of its Lord. So Allah sets forth parables for men, in order that they may receive admonition.
