لَقَدْ كَانَ فِي قَصَصِهِمْ عِبْرَةٌ لِّأُولِي الْأَلْبَابِ مَا كَانَ حَدِيثًا يُفْتَرَى وَلَكِن تَصْدِيقَ الَّذِي بَيْنَ يَدَيْهِ وَتَفْصِيلَ كُلِّ شَيْءٍ وَهُدًى وَرَحْمَةً لِّقَوْمٍ يُؤْمِنُونَ
There is certainly a moral in their accounts for those who possess intellect. This [Quran] is not a fabricated discourse; rather, it is a confirmation of what was [revealed] before it, and an elaboration of all things, and a guidance and mercy for a people who have faith.
