وَلَآ أَقُولُ لَكُمْ عِندِى خَزَآئِنُ ٱللَّهِ وَلَآ أَعْلَمُ ٱلْغَيْبَ وَلَآ أَقُولُ إِنِّى مَلَكٌۭ وَلَآ أَقُولُ لِلَّذِينَ تَزْدَرِىٓ أَعْيُنُكُمْ لَن يُؤْتِيَهُمُ ٱللَّهُ خَيْرًا ۖ ٱللَّهُ أَعْلَمُ بِمَا فِىٓ أَنفُسِهِمْ ۖ إِنِّىٓ إِذًۭا لَّمِنَ ٱلظَّٰلِمِينَ
I say not unto you: "I have the treasures of Allah" nor "I have knowledge of the Unseen," nor say I: "Lo! I am an angel!" Nor say I unto those whom your eyes scorn that Allah will not give them good - Allah knoweth best what is in their hearts - Lo! then indeed I should be of the wrong-doers.
Surah Hud(11:31)
