Surah Al-A'raf, Verse 188

قُل لَّآ أَمۡلِكُ لِنَفۡسِي نَفۡعٗا وَلَا ضَرًّا إِلَّا مَا شَآءَ ٱللَّهُۚ وَلَوۡ كُنتُ أَعۡلَمُ ٱلۡغَيۡبَ لَٱسۡتَكۡثَرۡتُ مِنَ ٱلۡخَيۡرِ وَمَا مَسَّنِيَ ٱلسُّوٓءُۚ إِنۡ أَنَا۠ إِلَّا نَذِيرٞ وَبَشِيرٞ لِّقَوۡمٖ يُؤۡمِنُونَ١٨٨

qul lā amliku linafsī nafʿan walā ḍarran illā mā shāa l-lahu walaw kuntu aʿlamu l-ghayba la-is'takthartu mina l-khayri wamā massaniya l-sūu in anā illā nadhīrun wabashīrun liqawmin yu'minūna

Say, "I hold not for myself [the power of] benefit or harm, except what Allāh has willed. And if I knew the unseen, I could have acquired much wealth, and no harm would have touched me. I am not except a warner and a bringer of good tidings to a people who believe."
