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

(1) Have they not observed things that Allah has created: (how) their shadows incline to the right and to the left, making prostration unto Allah, and they are lowly?

(2) Have you (O Muhammad صلى الله عليه وسلم) not observed the hypocrites who say to their friends among the people of the Scripture who disbelieve: "(By Allah) If you are expelled, we (too) indeed will go out with you, and we shall never obey any one against you; and if you are attacked (in fight), we shall indeed help you." But Allah is Witness that they verily are liars.
