Arabic text
لَقَدۡ كَانَ فِي قَصَصِهِمۡ عِبۡرَةٞ لِّأُوْلِي ٱلۡأَلۡبَٰبِۗ مَا كَانَ حَدِيثٗا يُفۡتَرَىٰ وَلَٰكِن تَصۡدِيقَ ٱلَّذِي بَيۡنَ يَدَيۡهِ وَتَفۡصِيلَ كُلِّ شَيۡءٖ وَهُدٗى وَرَحۡمَةٗ لِّقَوۡمٖ يُؤۡمِنُونَ
There was certainly in their stories a lesson for those of understanding. Never was it [i.e., the Qur’ān] a narration invented, but a confirmation of what was before it and a detailed explanation of all things and guidance and mercy for a people who believe.
