وَلَا أَقُولُ لَكُمْ عِنْدِي خَزَائِنُ اللَّهِ وَلَا أَعْلَمُ الْغَيْبَ وَلَا أَقُولُ إِنِّي مَلَكٌ وَلَا أَقُولُ لِلَّذِينَ تَزْدَرِي أَعْيُنُكُمْ لَنْ يُؤْتِيَهُمُ اللَّهُ خَيْرًا ۖ اللَّهُ أَعْلَمُ بِمَا فِي أَنْفُسِهِمْ ۖ إِنِّي إِذًا لَمِنَ الظَّالِمِينَ
"And I do not say unto you, `God's treasures are with me'; nor [do I say], `I know the reality which is beyond the reach of human perception'; nor do I say, 'Behold, I am an angel'; nor do I say of those whom your eyes hold in contempt, `Never will God grant them any good'- for God is fully aware of what is in their hearts. [Were I to speak thus,] verily, I would indeed be among the evildoers."
