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

(11) After this it is ye, the same people, who slay among yourselves, and banish a party of you from their homes; assist (Their enemies) against them, in guilt and rancour; and if they come to you as captives, ye ransom them, though it was not lawful for you to banish them. Then is it only a part of the Book that ye believe in, and do ye reject the rest? but what is the reward for those among you who behave like this but disgrace in this life?- and on the Day of Judgment they shall be consigned to the most grievous penalty. For Allah is not unmindful of what ye do.

(12) And when there comes to them a Book from Allah, confirming what is with them,- although from of old they had prayed for victory against those without Faith,- when there comes to them that which they (should) have recognised, they refuse to believe in it but the curse of Allah is on those without Faith.

(13) thou wilt indeed find them, of all people, most greedy of life,-even more than the idolaters: Each one of them wishes He could be given a life of a thousand years: But the grant of such life will not save him from (due) punishment. For Allah sees well all that they do.

(14) They followed what the evil ones gave out (falsely) against the power of Solomon: the blasphemers Were, not Solomon, but the evil ones, teaching men Magic, and such things as came down at babylon to the angels Harut and Marut. But neither of these taught anyone (Such things) without saying: "We are only for trial; so do not blaspheme." They learned from them the means to sow discord between man and wife. But they could not thus harm anyone except by Allah's permission. And they learned what harmed them, not what profited them. And they knew that the buyers of (magic) would have no share in the happiness of the Hereafter. And vile was the price for which they did sell their souls, if they but knew!

(15) O ye of Faith! Say not (to the Messenger) words of ambiguous import, but words of respect; and hearken (to him): To those without Faith is a grievous punishment.

(16) It is never the wish of those without Faith among the People of the Book, nor of the Pagans, that anything good should come down to you from your Lord. But Allah will choose for His special Mercy whom He will - for Allah is Lord of grace abounding.

(17) None of Our revelations do We abrogate or cause to be forgotten, but We substitute something better or similar: Knowest thou not that Allah Hath power over all things?

(18) Knowest thou not that to Allah belongeth the dominion of the heavens and the earth? And besides Him ye have neither patron nor helper.

(19) Would ye question your Messenger as Moses was questioned of old? but whoever changeth from Faith to Unbelief, Hath strayed without doubt from the even way.

(20) Say those without knowledge: "Why speaketh not Allah unto us? or why cometh not unto us a Sign?" So said the people before them words of similar import. Their hearts are alike. We have indeed made clear the Signs unto any people who hold firmly to Faith (in their hearts).
