Surah Al-An'am (The Cattle), Verse 50

قُلْ لَّاۤ اَقُوْلُ لَكُمْ عِنْدِیْ خَزَآىِٕنُ اللّٰهِ وَلَاۤ اَعْلَمُ الْغَیْبَ وَلَاۤ اَقُوْلُ لَكُمْ اِنِّیْ مَلَكٌ اِنْ اَتَّبِعُ اِلَّا مَا یُوْحٰۤی اِلَیَّ قُلْ هَلْ یَسْتَوِی الْاَعْمٰی وَالْبَصِیْرُ اَفَلَا تَتَفَكَّرُوْنَ 

Qul laaa aqoolu lakum 'indee khazaaa'inul laahi wa laaa a'lamul ghaiba wa laaa aqoolu lakum innee malakun in attabi'u illaa maa yoohaaa ilaiy; qul hal yastawil a'maa walbaseer; afalaa tatafakkaroon

“Say: "I tell you not that with me are the treasures of Allah, nor do I know what is hidden, nor do I tell you I am an angel. I but follow what is revealed to me." Say: "can the blind be held equal to the seeing?" Will ye then consider not?”
