The word(s) "guardian" appears 69 time(s) in 63 verse(s) in Quran in Muhammad Habib Shakir translation.

(61) And whoever does not accept the-Divine caller, he shall not escape in the earth and he shall not have guardians besides Him, these are in manifest error.

(62) He is Allah, besides Whom there is no god; the King, the Holy, the Giver of peace, the Granter of security, guardian over all, the Mighty, the Supreme, the Possessor of every greatness Glory be to Allah from what they set up (with Him).

(63) If you both turn to Allah, then indeed your hearts are already inclined (to this); and if you back up each other against him, then surely Allah it is Who is his guardian, and Jibreel and -the believers that do good, and the angels after that are the aiders.
