unity of divine message across prophets

وَتَقَطَّعُوٓا۟ أَمْرَهُم بَيْنَهُمْ ۖ كُلٌّ إِلَيْنَا رَٰجِعُونَ

And [yet] they divided their affair [i.e., that of their religion] among themselves, [but] all to Us will return.

كَذَّبَتْ قَبْلَهُمْ قَوْمُ نُوحٍ وَٱلْأَحْزَابُ مِنۢ بَعْدِهِمْ ۖ وَهَمَّتْ كُلُّ أُمَّةٍۭ بِرَسُولِهِمْ لِيَأْخُذُوهُ ۖ وَجَـٰدَلُوا۟ بِٱلْبَـٰطِلِ لِيُدْحِضُوا۟ بِهِ ٱلْحَقَّ فَأَخَذْتُهُمْ ۖ فَكَيْفَ كَانَ عِقَابِ

The people of Noah denied before them and the [disbelieving] factions after them, and every nation intended [a plot] for their messenger to seize him, and they disputed by [using] falsehood to [attempt to] invalidate thereby the truth. So I seized them, and how [terrible] was My penalty.
