The word(s) "liars" appears 31 time(s) in 31 verse(s) in Quran in Muhammad Habib Shakir translation.

(21) And Firon said: O chiefs! I do not know of any god for you besides myself; therefore kindle a fire for me, O Haman, for brick, then prepare for me a lofty building so that I may obtain knowledge of Musa's god, and most surely I think him to be one of the liars.

(22) And certainly We tried those before them, so Allah will certainly know those who are true and He will certainly know the liars.

(23) And those who disbelieve say to those who believe: Follow our path and we will bear your wrongs. And never shall they be the bearers of any of their wrongs; most surely they are liars.

(24) And if they call you a liar, truly apostles before you were called liars, and to Allah are all affairs returned.

(25) And if they call you a liar, so did those before them indeed call (their apostles) liars; their apostles had come to them with clear arguments, and with scriptures, and with the illuminating book.

(26) Allah has begotten; and most surely they are liars.

(27) There was none of them but called the apostles liars, so just was My retribution.

(28) Cursed be the liars,

(29) On the day that Allah will raise them up all, then they will swear to Him as they swear to you, and they think that they have something; now surely they are the liars.

(30) Have you not seen those who have become hypocrites? They say to those of their brethren who disbelieve from among the followers of the Book: If you are driven forth, we shall certainly go forth with you, and we will never obey any one concerning you, and if you are fought against, we will certainly help you, and Allah bears witness that they are most surely liars.
