The word(s) "hafiz" appears 3 time(s) in 3 verse(s) in Quran in Mohsin Khan translation.

(1) And he (Iblis - Satan) had no authority over them, - except that We might test him who believes in the Hereafter from him who is in doubt about it. And your Lord is a hafiz (Watchful) over everything. (All-Knower of everything i.e. He keeps record of every person as regards deeds, and then He will reward them accordingly).

(2) And as for those who take as Auliya' (guardians, supporters, helpers, lords, gods, protectors) others besides Him [i.e. they take false deities other than Allah as protectors, and they worship them] - Allah is hafiz (Protector, Watcher) over them (i.e. takes care of their deeds and will recompense them), and you (O Muhammad صلى الله عليه و سلم) are not a Wakil (guardian or a disposer of their affairs) over them (to protect their deeds).

(3) But if they turn away (O Muhammad صلى الله عليه و سلم from the Islamic Monotheism, which you have brought to them). We have not sent you (O Muhammad صلى الله عليه و سلم) as a hafiz (watcher, protector) over them (i.e. to take care of their deeds and to recompense them). Your duty is to convey (the Message). And verily, when We cause man to taste of Mercy from Us, he rejoices thereat; but when some ill befalls them because of the deeds which their hands have sent forth, then verily, man (becomes) ingrate!
