quran:54:25 –

Has the message been sent down upon him from among us? Rather, he is an insolent liar."  

Has the Reminder, the revelation, been cast (read a-ulqiya pronouncing both hamzas, or by not pronouncing the second one but in both cases inserting an intervening alif, or leaving this ˹insertion˺ out) upon him ˹alone˺ from among us?, in other words, nothing has been revealed to him. Nay, but he is a conceited, an arrogant and insolent, liar, in his saying that the mentioned has been revealed to him. God, exalted be He, says:
القرآن:٥٤:٢٥ –

أَأُلْقِيَ الذِّكْرُ عَلَيْهِ مِنْ بَيْنِنَا بَلْ هُوَ كَذَّابٌ أَشِرٌ  

{أألقي} بتحقيق الهمزتين وتسهيل الثانية وإدخال ألف بينهما على الوجهين وتركه {الذكر} الوحي {عليه من بيننا} أي لم يوح إليه {بل هو كذاب} في قوله إنه أوحي إليه ما ذكر {أشر} متكبر بطر، قال تعالى.
