﴿ قُل لَّآ أَقُولُ لَكُمْ عِندِى خَزَآئِنُ ٱللَّهِ وَلَآ أَعْلَمُ ٱلْغَيْبَ وَلَآ أَقُولُ لَكُمْ إِنِّى مَلَكٌ ۖ إِنْ أَتَّبِعُ إِلَّا مَا يُوحَىٰٓ إِلَىَّ ۚ قُلْ هَلْ يَسْتَوِى ٱلْأَعْمَىٰ وَٱلْبَصِيرُ ۚ أَفَلَا تَتَفَكَّرُونَ ﴾

“Say [O Prophet]: "I do not say unto you, 'God's treasures are with me,'; nor [do I say], 'I know the things that are beyond the reach of human perception'; nor do I say unto you, 'Behold, I am an angel': I but follow what is revealed to me." Say: "Can the blind and the seeing be deemed equal? Will you not, then, take thought?"”

The preacher of God’s word appears in the world not only as one who gives good news, but also as a warner. In other words, the basis on which a man is tested before God is that he should recognise the Truth conveyed in the language of admonition and reform himself accordingly. If he fails to recognise the Truth and demands magic feats and charms as a condition for acceptance, he merely proves his moral blindness; and for such blind people, there is no fate but havoc and destruction in this world of God.
