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

(201) The friends shall on that day be enemies one to another, except those who guard (against evil).

(202) Surely those who guard (against evil) are in a secure place,

(203) Before them is hell, and there shall not avail them aught of what they earned, nor those whom they took for guardians besides Allah, and they shall have a grievous punishment.

(204) Surely they shall not avail you in the least against Allah; and surely the unjust are friends of each other, and Allah is the guardian of those who guard (against evil).

(205) 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.

(206) A parable of the garden which those guarding (against evil) are promised: Therein are rivers of water that does not alter, and rivers of milk the taste whereof does not change, and rivers of drink delicious to those who drink, and rivers of honey clarified and for them therein are all fruits and protection from their Lord. (Are these) like those who abide in the fire and who are made to drink boiling water so it rends their bowels asunder.

(207) And (as for) those who follow the right direction, He increases them in guidance and gives them their guarding (against evil).

(208) The life of this world is only idle sport and play, and if you believe and guard (against evil) He will give you your rewards, and will not ask of you your possessions.

(209) When those who disbelieved harbored in their hearts (feelings of) disdain, the disdain of (the days of) ignorance, but Allah sent down His tranquillity on His Apostle and on the believers, and made them keep the word of guarding (against evil), and they were entitled to it and worthy of it; and Allah is Cognizant of all things.

(210) Surely those who lower their voices before Allah's Apostle are they whose hearts Allah has proved for guarding (against evil); they shall have forgiveness and a great reward.
