75:16-17
لَا تُحَرِّكْ بِهِ لِسَانَكَ لِتَعْجَلَ بِهِ إِنَّ عَلَيْنَا جَمْعَهُ وَقُرْآنَهُ
“Do not move your tongue with it to hasten it. Indeed, upon Us is its collection and recitation.”
The divine reassurance to the Prophet not to rush the recitation of revelation – Allah Himself guarantees its preservation in the Prophet's memory, laying the foundation of the Quran's oral transmission tradition.
75:36
أَيَحْسَبُ الْإِنسَانُ أَن يُتْرَكَ سُدًى
“Does man think that he will be left neglected?”
A piercing rhetorical challenge – the assumption that human beings are morally unaccountable is demolished in a single question, affirming that purposeful creation implies purposeful judgement.
