The word(s) "turning" appears 28 time(s) in 28 verse(s) in Quran in Abdullah Yusuf Ali translation.

(11) (He turned in mercy also) to the three who were left behind; (they felt guilty) to such a degree that the earth seemed constrained to them, for all its spaciousness, and their (very) souls seemed straitened to them,- and they perceived that there is no fleeing from Allah (and no refuge) but to Himself. Then He turned to them, that they might repent: for Allah is Oft-Returning, Most Merciful.

(12) They said, turning towards them: "What is it that ye miss?"

(13) For each (such person) there are (angels) in succession, before and behind him: They guard him by command of Allah. Allah does not change a people's lot unless they change what is in their hearts. But when (once) Allah willeth a people's punishment, there can be no turning it back, nor will they find, besides Him, any to protect.

(14) They running forward with necks outstretched, their heads uplifted, their gaze returning not towards them, and their hearts a (gaping) void!

(15) We sent them Our Signs, but they persisted in turning away from them.

(16) Thou wouldst have seen the sun, when it rose, declining to the right from their Cave, and when it set, turning away from them to the left, while they lay in the open space in the midst of the Cave. Such are among the Signs of Allah: He whom Allah, guides is rightly guided; but he whom Allah leaves to stray,- for him wilt thou find no protector to lead him to the Right Way.

(17) So his fruits (and enjoyment) were encompassed (with ruin), and he remained twisting and turning his hands over what he had spent on his property, which had (now) tumbled to pieces to its very foundations, and he could only say, "Woe is me! Would I had never ascribed partners to my Lord and Cherisher!"

(18) If it were not for Allah's grace and mercy on you, and that Allah is Oft-Returning, full of Wisdom,- (Ye would be ruined indeed).

(19) When trouble touches men, they cry to their Lord, turning back to Him in repentance: but when He gives them a taste of Mercy as from Himself, behold, some of them pay part-worship to other god's besides their Lord,-

(20) Call them by (the names of) their fathers: that is juster in the sight of Allah. But if ye know not their father's (names, call them) your Brothers in faith, or your maulas. But there is no blame on you if ye make a mistake therein: (what counts is) the intention of your hearts: and Allah is Oft-Returning, Most Merciful.
