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

(531) But there are, among men, those who purchase idle tales, without knowledge (or meaning), to mislead (men) from the Path of Allah and throw ridicule (on the Path): for such there will be a Humiliating Penalty.

(532) He created the heavens without any pillars that ye can see; He set on the earth mountains standing firm, lest it should shake with you; and He scattered through it beasts of all kinds. We send down rain from the sky, and produce on the earth every kind of noble creature, in pairs.

(533) "But if they strive to make thee join in worship with Me things of which thou hast no knowledge, obey them not; yet bear them company in this life with justice (and consideration), and follow the way of those who turn to me (in love): in the end the return of you all is to Me, and I will tell you the truth (and meaning) of all that ye did."

(534) "And be moderate in thy pace, and lower thy voice; for the harshest of sounds without doubt is the braying of the ass."

(535) Do ye not see that Allah has subjected to your (use) all things in the heavens and on earth, and has made his bounties flow to you in exceeding measure, (both) seen and unseen? Yet there are among men those who dispute about Allah, without knowledge and without guidance, and without a Book to enlighten them!

(536) If thou ask them, who it is that created the heavens and the earth. They will certainly say, "Allah". Say: "Praise be to Allah!" But most of them understand not.

(537) Seest thou not that Allah merges Night into Day and he merges Day into Night; that He has subjected the sun, and the moon (to his Law), each running its course for a term appointed; and that Allah is well-acquainted with all that ye do?

(538) Seest thou not that the ships sail through the ocean by the Grace of Allah?- that He may show you of His Signs? Verily in this are Signs for all who constantly persevere and give thanks.

(539) Or do they say, "He has forged it"? Nay, it is the Truth from thy Lord, that thou mayest admonish a people to whom no warner has come before thee: in order that they may receive guidance.

(540) He rules (all) affairs from the heavens to the earth: in the end will (all affairs) go up to Him, on a Day, the space whereof will be (as) a thousand years of your reckoning.
