The word(s) "stray" appears 97 time(s) in 91 verse(s) in Quran in Muhammad Pickthal translation.

(81) He whom Allah sendeth astray, for him there is no protecting friend after Him. And thou (Muhammad) wilt see the evil-doers when they see the doom, (how) they say: Is there any way of return?

(82) And they will have no protecting friends to help them instead of Allah. He whom Allah sendeth astray, for him there is no road.

(83) Hast thou seen him who maketh his desire his god, and Allah sendeth him astray purposely, and sealeth up his hearing and his heart, and setteth on his sight a covering? Then who will lead him after Allah (hath condemned him)? Will ye not then heed?

(84) And who is further astray than those who, instead of Allah, pray unto such as hear not their prayer until the Day of Resurrection, and are unconscious of their prayer,

(85) Such is their sum of knowledge. Lo! thy Lord is Best Aware of him who strayeth, and He is Best Aware of him whom goeth right.

(86) O ye who believe! Choose not My enemy and your enemy for allies. Do ye give them friendship when they disbelieve in that truth which hath come unto you, driving out the messenger and you because ye believe in Allah, your Lord? If ye have come forth to strive in My way and seeking My good pleasure, (show them not friendship). Do ye show friendship unto them in secret, when I am Best Aware of what ye hide and what ye proclaim? And whosoever doeth it among you, he verily hath strayed from the right way.

(87) And (remember) when Moses said unto his people: O my people! Why persecute ye me, when ye well know that I am Allah's messenger unto you? So when they went astray Allah sent their hearts astray. And Allah guideth not the evil-living folk.

(88) Lo! thy Lord is Best Aware of him who strayeth from His way, and He is Best Aware of those who walk aright.

(89) And they have led many astray, and Thou increasest the wrong-doers in naught save error.

(90) We have appointed only angels to be wardens of the Fire, and their number have We made to be a stumbling-block for those who disbelieve; that those to whom the Scripture hath been given may have certainty, and that believers may increase in faith; and that those to whom the Scripture hath been given and believers may not doubt; and that those in whose hearts there is disease, and disbelievers, may say: What meaneth Allah by this similitude? Thus Allah sendeth astray whom He will, and whom He will He guideth. None knoweth the hosts of thy Lord save Him. This is naught else than a Reminder unto mortals.
