The word(s) "behind" appears 62 time(s) in 60 verse(s) in Quran in Muhammad Pickthal translation.

(1) And when there cometh unto them a messenger from Allah, confirming that which they possess, a party of those who have received the Scripture fling the Scripture of Allah behind their backs as if they knew not,

(2) Such of you as die and leave behind them wives, they (the wives) shall wait, keeping themselves apart, four months and ten days. And when they reach the term (prescribed for them) then there is no sin for you in aught that they may do with themselves in decency. Allah is informed of what ye do.

(3) (In the case of) those of you who are about to die and leave behind them wives, they should bequeath unto their wives a provision for the year without turning them out, but if they go out (of their own accord) there is no sin for you in that which they do of themselves within their rights. Allah is Mighty, Wise.

(4) And their Prophet said unto them: Lo! the token of his kingdom is that there shall come unto you the ark wherein is peace of reassurance from your Lord, and a remnant of that which the house of Moses and the house of Aaron left behind, the angels bearing it. Lo! herein shall be a token for you if (in truth) ye are believers.

(5) Allah! There is no deity save Him, the Alive, the Eternal. Neither slumber nor sleep overtaketh Him. Unto Him belongeth whatsoever is in the heavens and whatsoever is in the earth. Who is he that intercedeth with Him save by His leave? He knoweth that which is in front of them and that which is behind them, while they encompass nothing of His knowledge save what He will. His throne includeth the heavens and the earth, and He is never weary of preserving them. He is the Sublime, the Tremendous.

(6) Jubilant (are they) because of that which Allah hath bestowed upon them of His bounty, rejoicing for the sake of those who have not joined them but are left behind: That there shall no fear come upon them neither shall they grieve.

(7) And (remember) when Allah laid a charge on those who had received the Scripture (He said): Ye are to expound it to mankind and not to hide it. But they flung it behind their backs and bought thereby a little gain. Verily evil is that which they have gained thereby.

(8) And let those fear (in their behaviour toward orphans) who if they left behind them weak offspring would be afraid for them. So let them mind their duty to Allah, and speak justly.

(9) Now have ye come unto Us solitary as We did create you at the first, and ye have left behind you all that We bestowed upon you, and We behold not with you those your intercessors, of whom ye claimed that they possessed a share in you. Now is the bond between you severed, and that which ye presumed hath failed you.

(10) Then I shall come upon them from before them and from behind them and from their right hands and from their left hands, and Thou wilt not find most of them beholden (unto Thee).
