﴿وَلَكِنَّا أَنْشَأْنَا قُرُونًا فَتَطَاوَلَ عَلَيْهِمُ الْعُمر﴾ كَانَ بَين عِيسَى وَمُحَمّد خَمْسمِائَة سنة، وَقيل: سِتّمائَة سَنَةٍ ﴿وَمَا كُنْتَ ثَاوِيًا فِي أَهْلِ مَدْيَنَ تَتْلُو عَلَيْهِمْ آيَاتِنَا﴾ أَيْ: لَمْ تَكُنْ يَا مُحَمَّدُ مُقِيمًا بِمَدْيَنَ؛ فَتَعْلَمَ كَيْفَ كَانَ أَمْرُهُمْ، فَتُخْبِرَ أَهْلَ مَكَّةَ بِشَأْنِهِمْ وَأمرهمْ
