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

(111) For his sake there are angels following one another, before him and behind him, who guard him by Allah's commandment; surely Allah does not change the condition of a people until they change their own condition; and when Allah intends evil to a people, there is no averting it, and besides Him they have no protector.

(112) Say: Who is the Lord of the heavens and the earth?-- Say: Allah. Say: Do you take then besides Him guardians who do not control any profit or harm for themselves? Say: Are the blind and the seeing alike? Or can the darkness and the light be equal? Or have they set up with Allah associates who have created creation like His, so that what is created became confused to them? Say: Allah is the Creator of all things, and He is the One, the Supreme.

(113) A likeness of the garden which the righteous are promised; there now beneath it rivers, its food and shades are perpetual; this is the requital of those who guarded (against evil), and the requital of the unbelievers is the fire.

(114) And thus have We revealed it, a true judgment in Arabic, and if you follow their low desires after what has come to you of knowledge, you shall not have against Allah any guardian or a protector.

(115) Surely We have revealed the Reminder and We will most surely be its guardian.

(116) And We guard it against every accursed Shaitan,

(117) Surely those who guard (against evil) shall be in the midst of gardens and fountains:

(118) And guard against (the punishment of) Allah and do not put me to shame.

(119) And it is said to those who guard (against evil): What is it that your Lord has revealed? They say, Good. For those who do good in this world is good, and certainly the abode of the hereafter is better; and certainly most excellent is the abode of those who guard (against evil);

(120) The gardens of perpetuity, they shall enter them, rivers flowing beneath them; they shall have in them what they please. Thus does Allah reward those who guard (against evil),
