قُل لَّوْ شَاءَ اللَّهُ مَا تَلَوْتُهُ عَلَيْكُمْ وَلَا أَدْرَاكُم بِهِ فَقَدْ لَبِثْتُ فِيكُمْ عُمُرًا مِّن قَبْلِهِ أَفَلَا تَعْقِلُونَ
Say, ‘Had Allah [so] wished, I would not have recited it to you, nor would He have made it known to you, for I have dwelled among you for a lifetime before it. Do you not exercise your reason?’
Agha Ali Puya Commentary
Commentary on Quran 10:16
[Pooya/Ali Commentary 10:16] The Holy Prophet had lived his whole life of purity and virtue amongst his people, and they knew and acknowledged it before he declared his divine mission. His fair character and honourable bearing won the approbation of the fellow citizens; and he received the title, by common consent, of al-amin (the trusted) and al-sadiq (the truthful). The Holy Prophet's truthfulness was a byword in Makka. Then under Allah's command he preached the unity of Allah and denounced idolatry.
