وَلَقَدْ أَرْسَلْنَا رُسُلًۭا 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
Verily We sent messengers before thee, among them those of whom We have told thee, and some of whom We have not told thee; and it was not given to any messenger that he should bring a portent save by Allah's leave, but when Allah's commandment cometh (the cause) is judged aright, and the followers of vanity will then be lost.
Surah Ghafir(40:78)
