The Heights - 7:188 "Say: "I can neither benefit nor harm myself except what Allah wills. Had I known the secret, I would have increased my wealth and no evil would have touched me. I am but a bearer of glad tidings and a warner to a people who believe."
related verse:
Prophet Hud/11:31 I do not say that the treasures of Allah are with me, nor do I know the secret, nor do I claim to be an angel, nor do I say that Allah will not grant any favor to those whom your eyes despise. Allah knows better their secret thoughts. Otherwise I would be of the wrongdoers.
وَلَٓا اَقُولُ لَكُمْ عِنْد۪ي خَزَٓائِنُ اللّٰهِ وَلَٓا اَعْلَمُ الْغَيْبَ وَلَٓا اَقُولُ اِنّ۪ي مَلَكٌ وَلَٓا اَقُولُ لِلَّذ۪ينَ تَزْدَر۪ٓي اَعْيُنُكُمْ لَنْ يُؤْتِيَهُمُ اللّٰهُ خَيْراًۜ اَللّٰهُ اَعْلَمُ بِمَا ف۪ٓي اَنْفُسِهِمْۚ اِنّ۪ٓي اِذاً لَمِنَ الظَّالِم۪ينَ

The Cattle/6:50 "Say: "I do not tell you that the treasures of Allah are with me. Nor do I know the secrets. Nor do I tell you that I am an angel. I only follow what has been revealed to me."Say also: "Are the blind and the seeing alike?"Do you not think?"
قُلْ لَٓا اَقُولُ لَكُمْ عِنْد۪ي خَزَٓائِنُ اللّٰهِ وَلَٓا اَعْلَمُ الْغَيْبَ وَلَٓا اَقُولُ لَكُمْ اِنّ۪ي مَلَكٌۚ اِنْ اَتَّبِعُ اِلَّا مَا يُوحٰٓى اِلَيَّۜ قُلْ هَلْ يَسْتَوِي الْاَعْمٰى وَالْبَص۪يرُۜ اَفَلَا تَتَفَكَّرُونَ۟

قُلْ لَٓا اَمْلِكُ لِنَفْس۪ي نَفْعاً وَلَا ضَراًّ اِلَّا مَا شَٓاءَ اللّٰهُۜ وَلَوْ كُنْتُ اَعْلَمُ الْغَيْبَ لَاسْتَكْثَرْتُ مِنَ الْخَيْرِۚ وَمَا مَسَّنِيَ السُّٓوءُ اِنْ اَنَا۬ اِلَّا نَذ۪يرٌ وَبَش۪يرٌ لِقَوْمٍ يُؤْمِنُونَ۟
