قُل لَّا أَمْلِكُ لِنَفْسِي نَفْعًا وَلَا ضَرًّا إِلَّا مَا شَاءَ اللَّهُ ۚ وَلَوْ كُنتُ أَعْلَمُ الْغَيْبَ لَاسْتَكْثَرْتُ مِنَ الْخَيْرِ وَمَا مَسَّنِيَ السُّوءُ ۚ إِنْ أَنَا إِلَّا نَذِيرٌ وَبَشِيرٌ لِّقَوْمٍ يُؤْمِنُونَ
Qul la amliku linafsee nafAAan wala darran illa ma shaa Allahu walaw kuntu aAAlamu alghayba laistakthartu mina alkhayri wama massaniya alssooo in ana illa natheerun wabasheerun liqawmin yuminoona
Say: "I have no power over any good or harm to myself except as Allah willeth. If I had knowledge of the unseen, I should have multiplied all good, and no evil should have touched me: I am but a warner, and a bringer of glad tidings to those who have faith."
