Sura al-Qamar 54:25

أَءُلْقِىَ ٱلذِّكْرُ عَلَيْهِ مِنۢ بَيْنِنَا بَلْ هُوَ كَذَّابٌ أَشِرٌ

a-ulqiya l-dhikru ʿalayhi min bayninā bal huwa kadhdhābun ashirun

"Is it that the Message is sent to him, of all people amongst us? Nay, he is a liar, an insolent one!"

Sura al-Qamar 54:26

سَيَعْلَمُونَ غَدًا مَّنِ ٱلْكَذَّابُ ٱلْأَشِرُ

sa-yaʿlamūna ghadan mani l-kadhdhābu l-ashiru

Ah! they will know on the morrow, which is the liar, the insolent one!
