The word(s) "guard" appears 249 time(s) in 233 verse(s) in Quran in Muhammad Habib Shakir translation.

(191) So He ordained them seven heavens in two periods, and revealed in every heaven its affair; and We adorned the lower heaven with brilliant stars and (made it) to guard; that is the decree of the Mighty, the Knowing.

(192) And We delivered those who believed and guarded (against evil).

(193) We are your guardians in this world's life and in the hereafter, and you shall have therein what your souls desire and you shall have therein what you ask for:

(194) And (as for) those who take guardians besides Him, Allah watches over them, and you have not charge over them.

(195) And if Allah had pleased He would surely have made them a single community, but He makes whom He pleases enter into His mercy, and the unjust it is that shall have no guardian or helper.

(196) Or have they taken guardians besides Him? But Allah is the guardian, and He gives life to the dead, and He has power over all things.

(197) And He it is Who sends down the rain after they have despaired, and He unfolds His mercy; and He is the guardian, the Praised One.

(198) And you cannot escape in the earth, and you shall not have a guardian or a helper besides Allah.

(199) And whomsoever Allah makes err, he has no guardian after Him; and you shall see the unjust, when they see the punishment, saying: Is there any way to return?

(200) And (other) embellishments of gold; and all this is naught but provision of this world's life, and the hereafter is with your Lord only for those who guard (against evil).
