وَمَا كَانَ ہٰذَا الْقُرْاٰنُ اَنْ يُّفْتَرٰي مِنْ دُوْنِ اللہِ وَلٰكِنْ تَصْدِيْقَ الَّذِيْ بَيْنَ يَدَيْہِ وَتَفْصِيْلَ الْكِتٰبِ لَا رَيْبَ فِيْہِ مِنْ رَّبِّ الْعٰلَمِيْنَ۳۷ۣ
Wama kana hatha alquranu an yuftara min dooni Allahi walakin tasdeeqa allathee bayna yadayhi watafseela alkitabi la rayba feehi min rabbi alAAalameena
This Qur'an is not such (a writ) as could be composed by anyone but God. It confirms what has been revealed before, and is an exposition of (Heaven's) law. Without any doubt it's from the Lord of all the worlds.
