The word(s) "guarding" appears 14 time(s) in 14 verse(s) in Quran in Muhammad Habib Shakir translation.

(11) 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.

(12) 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.

(13) O you who believe! when you confer together in private, do not give to each other counsel of sin and revolt and disobedience to the Apostle, and give to each other counsel of goodness and guarding (against evil); and be careful of (your duty to) Allah, to Whom you shall be gathered together.

(14) Or enjoined guarding (against evil)?
