The word(s) "tur" appears 545 time(s) in 501 verse(s) in Quran in Abdullah Yusuf Ali translation.

(411) We destroyed aforetime populations round about you; and We have shown the Signs in various ways, that they may turn (to Us).

(412) Behold, We turned towards thee a company of Jinns (quietly) listening to the Qur'an: when they stood in the presence thereof, they said, "Listen in silence!" When the (reading) was finished, they returned to their people, to warn (them of their sins).

(413) Those who turn back as apostates after Guidance was clearly shown to them,- the Evil One has instigated them and busied them up with false hopes.

(414) Behold, ye are those invited to spend (of your substance) in the Way of Allah: But among you are some that are niggardly. But any who are niggardly are so at the expense of their own souls. But Allah is free of all wants, and it is ye that are needy. If ye turn back (from the Path), He will substitute in your stead another people; then they would not be like you!

(415) "Nay, ye thought that the Messenger and the Believers would never return to their families; this seemed pleasing in your hearts, and ye conceived an evil thought, for ye are a people lost (in wickedness)."

(416) Say to the desert Arabs who lagged behind: "Ye shall be summoned (to fight) against a people given to vehement war: then shall ye fight, or they shall submit. Then if ye show obedience, Allah will grant you a goodly reward, but if ye turn back as ye did before, He will punish you with a grievous Penalty."

(417) No blame is there on the blind, nor is there blame on the lame, nor on one ill (if he joins not the war): But he that obeys Allah and his Messenger,- (Allah) will admit him to Gardens beneath which rivers flow; and he who turns back, (Allah) will punish him with a grievous Penalty.

(418) If the Unbelievers should fight you, they would certainly turn their backs; then would they find neither protector nor helper.

(419) O ye who believe! Avoid suspicion as much (as possible): for suspicion in some cases is a sin: And spy not on each other behind their backs. Would any of you like to eat the flesh of his dead brother? Nay, ye would abhor it... But fear Allah: For Allah is Oft-Returning, Most Merciful.

(420) "What! When we die and become dust, (shall we live again?) That is a (sort of) return far (from our understanding)."
