Quranic guidance

وَمَا مِن دَآبَّةٍ فِى ٱلْأَرْضِ وَلَا طَـٰٓئِرٍ يَطِيرُ بِجَنَاحَيْهِ إِلَّآ أُمَمٌ أَمْثَالُكُم ۚ مَّا فَرَّطْنَا فِى ٱلْكِتَـٰبِ مِن شَىْءٍ ۚ ثُمَّ إِلَىٰ رَبِّهِمْ يُحْشَرُونَ

And there is no creature on [or within] the earth or bird that flies with its wings except [that they are] communities like you. We have not neglected in the Register a thing. Then unto their Lord they will be gathered.

وَٱتَّبِعُوٓا۟ أَحْسَنَ مَآ أُنزِلَ إِلَيْكُم مِّن رَّبِّكُم مِّن قَبْلِ أَن يَأْتِيَكُمُ ٱلْعَذَابُ بَغْتَةً وَأَنتُمْ لَا تَشْعُرُونَ

And follow the best of what was revealed to you from your Lord [i.e., the Qur’ān] before the punishment comes upon you suddenly while you do not perceive,

قَالُوا۟ يَـٰقَوْمَنَآ إِنَّا سَمِعْنَا كِتَـٰبًا أُنزِلَ مِنۢ بَعْدِ مُوسَىٰ مُصَدِّقًا لِّمَا بَيْنَ يَدَيْهِ يَهْدِىٓ إِلَى ٱلْحَقِّ وَإِلَىٰ طَرِيقٍ مُّسْتَقِيمٍ

They said, "O our people, indeed we have heard a [recited] Book revealed after Moses confirming what was before it which guides to the truth and to a straight path.

فَبِأَىِّ حَدِيثٍۭ بَعْدَهُۥ يُؤْمِنُونَ

Then in what statement after it [i.e., the Qur’ān] will they believe?
