Prophethood and evidence

قُل لَّوْ شَآءَ ٱللَّهُ مَا تَلَوْتُهُۥ عَلَيْكُمْ وَلَآ أَدْرَىٰكُم بِهِۦ ۖ فَقَدْ لَبِثْتُ فِيكُمْ عُمُرًا مِّن قَبْلِهِۦٓ ۚ أَفَلَا تَعْقِلُونَ

Say, "If Allāh had willed, I would not have recited it to you, nor would He have made it known to you, for I had remained among you a lifetime before it. Then will you not reason?"

فَأَلْقَىٰ عَصَاهُ فَإِذَا هِىَ ثُعْبَانٌ مُّبِينٌ

So [Moses] threw his staff, and suddenly it was a serpent manifest.
