Quran 7:188 from Surah Al-A'raaf on Divine Marvels.
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 يُؤۡمِنُونَ
English translation: Say Not I have power for myself (to) benefit and no (power to) harm except what wills Allah And if I would know (of) the unseen surely I could have multiplied of the good and not (could) have touched me the evil Not (am) I except a warner and a bearer of good tidings to a people who believe
Transliteration: qul la amliku linafsi naf 'an wala darran illa ma shaa al-lahu walaw kuntu a'lamu al-ghayba la-is'takthartu mina al-khayri wama massaniya al-suu in ana illa nadhirun wabashirun liqawmin yu'minuna
