The word(s) "both" appears 78 time(s) in 73 verse(s) in Quran in Muhammad Habib Shakir translation.

(51) And We have enjoined man in respect of his parents-- his mother bears him with faintings upon faintings and his weaning takes two years-- saying: Be grateful to Me and to both your parents; to Me is the eventual coming.

(52) When We sent to them two, they rejected both of them, then We strengthened (them) with a third, so they said: Surely we are apostles to you.

(53) So when they both submitted and he threw him down upon his forehead,

(54) And We delivered them both and their people from the mighty distress.

(55) And We gave them both the Book that made (things) clear.

(56) And We guided them both on the right way.

(57) Surely they were both of Our believing servants.

(58) Then He directed Himself to the heaven and it is a vapor, so He said to it and to the earth: Come both, willingly or unwillingly. They both said: We come willingly.

(59) And one of His signs is the creation of the heavens and the earth and what He has spread forth in both of them of living beings; and when He pleases He is all-powerful to gather them together.

(60) Or He makes them of both sorts, male and female; and He makes whom He pleases barren; surely He is the Knowing, the Powerful.
