Al-A'raf - 7:20

فَوَسْوَسَ لَهُمَا الشَّيْطَانُ لِيُبْدِيَ لَهُمَا مَا وُورِيَ عَنْهُمَا مِن سَوْءَاتِهِمَا وَقَالَ مَا نَهَاكُمَا رَبُّكُمَا عَنْ هَـذِهِ الشَّجَرَةِ إِلاَّ أَن تَكُونَا مَلَكَيْنِ أَوْ تَكُونَا مِنَ الْخَالِدِينَ
[7:20]
But the Shaitan made an evil suggestion to them that he might make manifest to them what had been hidden from them of their evil inclinations, and he said: Your Lord has not forbidden you this tree except that you may not both become two angels or that you may (not) become of the immortals.
Then began Satan to whisper suggestions to them, bringing openly before their minds all their shame that was hidden from them (before): he said: "Your Lord only forbade you this tree, lest ye should become angels or such beings as live for ever."
Then Satan whispered to them that he might manifest unto them that which was hidden from them of their shame, and he said: Your Lord forbade you from this tree only lest ye should become angels or become of the immortals.
