quran:21:7 –

And We sent not before you, ˹O Muhammad˺, except men to whom We revealed ˹the message˺, so ask the people of the message if you do not know.  

And We sent none before you other than men to whom We revealed (read nūhī or yūhā, ‘˹to whom˺ it is revealed’) and ˹We sent˺ not any angels. Ask the People of the Remembrance, those with knowledge of the Torah and the Gospel, if you do not know, this; for they will know it. Since you are more likely to believe them than the believers are to believing Muhammad (s).
القرآن:٢١:٧ –

وَمَا أَرْسَلْنَا قَبْلَكَ إِلَّا رِجَالًا نُوحِي إِلَيْهِمْ ۖ فَاسْأَلُوا أَهْلَ الذِّكْرِ إِنْ كُنْتُمْ لَا تَعْلَمُونَ  

{وما أرسلنا قبلك إلا رجالاً نوحي} وفي قراءة بالياء وفتح الحاء {إليهم} لا ملائكة {فاسألوا أهل الذكر} العلماء بالتوراة والإنجيل {إن كنتم لا تعلمون} ذلك فإنهم يعلمونه، وأنتم إلى تصديقهم أقرب من تصديق المؤمنين بمحمد.
