وَلَقَدْ أَرْسَلْنَا رُسُلًا مِّن قَبْلِكَ مِنْهُم مَّن قَصَصْنَا عَلَيْكَ وَمِنْهُم مَّن لَّمْ نَقْصُصْ عَلَيْكَ ۗ وَمَا كَانَ لِرَسُولٍ أَن يَأْتِىَ بِـَٔايَةٍ إِلَّا بِإِذْنِ ٱللَّهِ ۚ فَإِذَا جَآءَ أَمْرُ ٱللَّهِ قُضِىَ بِٱلْحَقِّ وَخَسِرَ هُنَالِكَ ٱلْمُبْطِلُونَ 78

And it was not for any messenger to bring a sign [or verse] except by permission of Allāh. So when the command of Allāh comes, it will be concluded [i.e., judged] in truth, and the falsifiers will thereupon lose [all].
