Surah Al-Araf Verse 20 - English Translation by Shabbir Ahmed
Surah Al-Arafفَوَسۡوَسَ لَهُمَا ٱلشَّيۡطَٰنُ لِيُبۡدِيَ لَهُمَا مَا وُۥرِيَ عَنۡهُمَا مِن سَوۡءَٰتِهِمَا وَقَالَ مَا نَهَىٰكُمَا رَبُّكُمَا عَنۡ هَٰذِهِ ٱلشَّجَرَةِ إِلَّآ أَن تَكُونَا مَلَكَيۡنِ أَوۡ تَكُونَا مِنَ ٱلۡخَٰلِدِينَ
Then Satan deceived them in order to reveal their imperfections and fallibility to them. He said, "Your Lord forbade this tree lest you become angels or become immortals." (The selfish desire of humans prompted them to think about their own children rather than the collective good. That would, in a way, give them power and immortality)
