Al A’raf Ayah 188

قُل لَّآ أَمْلِكُ لِنَفْسِى نَفْعًا وَلَا ضَرًّا إِلَّا مَا شَآءَ ٱللَّهُ‌ۚ وَلَوْ كُنتُ أَعْلَمُ ٱلْغَيْبَ لَٱسْتَكْثَرْتُ مِنَ ٱلْخَيْرِ وَمَا مَسَّنِىَ ٱلسُّوٓءُ‌ۚ إِنْ أَنَا۟ إِلَّا نَذِيرٌ وَبَشِيرٌ لِّقَوْمٍ يُؤْمِنُونَ ١٨٨ Say, “I have no power to benefit or protect myself, except by the Will of Allah. If I had known the unknown, I would have benefited myself enormously, and no harm would have ever touched me. I am only a warner and deliverer of good news for those who believe.”
