The word(s) "watch" appears 25 time(s) in 24 verse(s) in Quran in Mohsin Khan translation.

(11) It is not lawful for you (to marry other) women after this, nor to change them for other wives even though their beauty attracts you, except those (slaves) whom your right hand possesses. And Allah is Ever a watcher over all things.

(12) 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).

(13) And watch them and they shall see (the punishment)!

(14) And watch and they shall see (the torment)!

(15) 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).

(16) 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!

(17) Not a word does he (or she) utter but there is a watcher by him ready (to record it).

(18) Verily, We are sending the she-camel as a test for them. So watch them [O Salih عليه السلام], and be patient!

(19) He is Allah beside Whom La ilaha illa Huwa (none has the right to be worshipped but He), the King, the Holy, the One Free from all defects, the Giver of security, the watcher over His creatures, the All-Mighty, the Compeller, the Supreme. Glory be to Allah! (High is He) above all that they associate as partners with Him.

(20) 'And verily, we used to sit there in stations, to (steal) a hearing, but any who listens now will find a flaming fire watching him in ambush.
