The word(s) "tur" appears 640 time(s) in 582 verse(s) in Quran in Mohsin Khan translation.

(71) Lo! You are the ones who love them but they love you not, and you believe in all the Scriptures [i.e. you believe in the Taurat (Torah) and the Injeel (Gospel), while they disbelieve in your Book, the Qur'an]. And when they meet you, they say, "We believe." But when they are alone, they bite the tips of their fingers at you in rage. Say: "Perish in your rage. Certainly, Allah knows what is in the breasts (all the secrets)."

(72) Not for you (O Muhammad صلى الله عليه وسلم, but for Allah) is the decision; whether He turns in mercy to (pardons) them or punishes them; verily, they are the Zalimun (polytheists, disobedients, and wrong-doers).

(73) If a wound (and killing) has touched you, be sure a similar wound (and killing) has touched the others. And so are the days (good and not so good), We give to men by turns, that Allah may test those who believe, and that He may take martyrs from among you. And Allah likes not the Zalimun (polytheists and wrong-doers).

(74) Muhammad (صلى الله عليه وسلم) is no more than a Messenger, and indeed (many) Messengers have passed away before him. If he dies or is killed, will you then turn back on your heels (as disbelievers)? And he who turns back on his heels, not the least harm will he do to Allah; and Allah will give reward to those who are grateful.

(75) O you who believe! If you obey those who disbelieve, they will send you back on your heels, and you will turn back (from Faith) as losers.

(76) Those of you who turned back on the day the two hosts met (i.e. the battle of Uhud), it was Shaitan (Satan) who caused them to backslide (run away from the battlefield) because of some (sins) they had earned. But Allah, indeed, has forgiven them. Surely, Allah is Oft-Forgiving, Most Forbearing.

(77) So they returned with Grace and Bounty from Allah. No harm touched them; and they followed the good Pleasure of Allah. And Allah is the Owner of Great Bounty.

(78) Then if they reject you (O Muhammad صلى الله عليه وسلم), so were Messengers rejected before you, who came with Al-Bayyinat (clear signs, proofs, evidence) and the Scripture and the Book of Enlightenment.

(79) You shall certainly be tried and tested in your wealth and properties and in your personal selves, and you shall certainly hear much that will grieve you from those who received the Scripture before you (Jews and Christians) and from those who ascribe partners to Allah; but if you persevere patiently, and become Al-Muttaqun (the pious - See V.2:2) then verily, that will be a determining factor in all affairs (and that is from the great matters which you must hold on with all your efforts).

(80) (And remember) when Allah took a covenant from those who were given the Scripture (Jews and Christians) to make it (the news of the coming of Prophet Muhammad صلى الله عليه وسلم and the religious knowledge) known and clear to mankind, and not to hide it, but they threw it away behind their backs, and purchased with it some miserable gain! And indeed worst is that which they bought.
