The word(s) "back" appears 262 time(s) in 241 verse(s) in Quran in Muhammad Habib Shakir translation.

(191) And if you should ask them who created them, they would certainly say: Allah. Whence are they then turned back?

(192) Yet they turned their backs on him and said: One taught (by others), a madman.

(193) So bring our fathers (back), if you are truthful.

(194) Whoever does good, it is for his own soul, and whoever does evil, it is against himself; then you shall be brought back to your-- Lord.

(195) And when Our clear communications are recited to them, their argument is no other than that they say: Bring our fathers (back) if you are truthful.

(196) And for all are degrees according to what they did, and that He may pay them back fully their deeds and they shall not be wronged.

(197) And when We turned towards you a party of the jinn who listened to the Quran; so when they came to it, they said: Be silent; then when it was finished, they turned back to their people warning (them).

(198) Surely (as for) those who return on their backs after that guidance has become manifest to them, the Shaitan has made it a light matter to them; and He gives them respite.

(199) But how will it be when the angels cause them to die smiting their backs.

(200) Behold! you are those who are called upon to spend in Allah's way, but among you are those who are niggardly, and whoever is niggardly is niggardly against his own soul; and Allah is Self-sufficient and you have need (of Him), and if you turn back He will bring in your place another people, then they will not be like you.
