The word(s) "both" appears 58 time(s) in 56 verse(s) in Quran in Abdullah Yusuf Ali translation.

(51) And the herbs and the trees - both (alike) prostrate in adoration.

(52) Soon shall We settle your affairs, O both ye worlds!

(53) Allah has indeed heard (and accepted) the statement of the woman who pleads with thee concerning her husband and carries her complaint (in prayer) to Allah: and Allah (always) hears the arguments between both sides among you: for Allah hears and sees (all things).

(54) If any men among you divorce their wives by Zihar (calling them mothers), they cannot be their mothers: None can be their mothers except those who gave them birth. And in fact they use words (both) iniquitous and false: but truly Allah is one that blots out (sins), and forgives (again and again).

(55) The end of both will be that they will go into the Fire, dwelling therein for ever. Such is the reward of the wrong-doers.

(56) Allah is He, than Whom there is no other god;- Who knows (all things) both secret and open; He, Most Gracious, Most Merciful.
