The word(s) "liars" appears 28 time(s) in 28 verse(s) in Quran in Mohsin Khan translation.

(21) Fir'aun (Pharaoh) said: "O chiefs! I know not that you have an ilah (a god) other than me. So kindle for me (a fire), O Haman, to bake (bricks out of) clay, and set up for me a Sarh (a lofty tower, or palace) in order that I may look at (or look for) the Ilah (God) of Musa (Moses); and verily, I think that he [Musa (Moses)] is one of the liars."

(22) And We indeed tested those who were before them. And Allah will certainly make (it) known (the truth of) those who are true, and will certainly make (it) known (the falsehood of) those who are liars, (although Allah knows all that before putting them to test).

(23) And those who disbelieve say to those who believe: "Follow our way and we will verily bear your sins." Never will they bear anything of their sins. Surely, they are liars.

(24) "Allah has begotten [offspring - the angels being the daughters of Allah)?" And, verily, they are liars!

(25) Cursed be the liars

(26) On the Day when Allah will resurrect them all together (for their account); then they will swear to Him as they swear to you (O Muslims). And they think that they have something (to stand upon). Verily, they are liars!

(27) 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.

(28) When the hypocrites come to you (O Muhammad صلى الله عليه وسلم), they say: "We bear witness that you are indeed the Messenger of Allah." Allah knows that you are indeed His Messenger, and Allah bears witness that the hypocrites are liars indeed.
