Surah An-Nahl, ayah 105

16:105

إِنَّمَا يَفۡتَرِي ٱلۡكَذِبَ ٱلَّذِينَ لَا يُؤۡمِنُونَ بِـَٔايَٰتِ ٱللَّهِۖ وَأُوْلَٰٓئِكَ هُمُ ٱلۡكَٰذِبُونَ ١٠٥

Innamā yaftaril-kadhibal-ladhīna lā yu'minūna bi'āyātillāhi wa ulā'ika humul-kādhibūn

They only invent falsehood who do not believe in the verses of Allāh, and it is those who are the liars.
