The word(s) "discourage" appears 2 time(s) in 2 verse(s) in Quran in Mohsin Khan translation.

(1) (And remember) when Allah showed them to you as few in your (i.e. Muhammad's صلى الله عليه وسلم) dream; if He had shown them to you as many, you would surely have been discouraged, and you would surely have disputed in making a decision. But Allah saved (you). Certainly, He is the All-Knower of what is in the breasts.

(2) So be patient (O Muhammad صلى الله عليه وسلم). Verily, the Promise of Allah is true; and let not those who have no certainty of faith, discourage you from conveying Allah's Message (which you are obliged to convey).
