The word(s) "back" appears 101 time(s) in 98 verse(s) in Quran in Muhammad Pickthal translation.

(81) Bring back our fathers, if ye speak the truth!

(82) Whoso doeth right, it is for his soul, and whoso doeth wrong, it is against it. And afterward unto your Lord ye will be brought back.

(83) And when Our clear revelations are recited unto them their only argument is that they say: Bring (back) our fathers. then, if ye are truthful.

(84) And when We inclined toward thee (Muhammad) certain of the jinn, who wished to hear the Qur'an and, when they were in its presence, said: Give ear! and, when it was finished, turned back to their people, warning.

(85) Lo! those who turn back after the guidance hath been manifested unto them, Satan hath seduced them, and He giveth them the rein.

(86) Then how (will it be with them) when the angels gather them, smiting their faces and their backs!

(87) There is no blame for the blind, nor is there blame for the lame, nor is there blame for the sick (that they go not forth to war). And whoso obeyeth Allah and His messenger, He will make him enter Gardens underneath which rivers flow; and whoso turneth back, him will He punish with a painful doom.

(88) O ye who believe! Shun much suspicion; for lo! some suspicion is a crime. And spy not, neither backbite one another. Would one of you love to eat the flesh of his dead brother? Ye abhor that (so abhor the other)! And keep your duty (to Allah). Lo! Allah is Relenting, Merciful.

(89) When we are dead and have become dust (shall we be brought back again)? That would be a far return!

(90) Do ye not force it back, if ye are truthful?
