20:2

20:117
فَقُلْنَا يَا آدَمُ إِنَّ هَذَا عَدُوٌّ لَّكَ وَلِزَوْجِكَ فَلَا يُخْرِجَنَّكُمَا مِنَ الْجَنَّةِ فَتَشْقَى
Then We said: "O Adam! verily, this is an enemy to thee and thy wife: so let him not get you both out of the Garden, so that thou art landed in misery.
20:123
قَالَ اهْبِطَا مِنْهَا جَمِيعاً بَعْضُكُمْ لِبَعْضٍ عَدُوٌّ فَإِمَّا يَأْتِيَنَّكُم مِّنِّي هُدًى فَمَنِ اتَّبَعَ هُدَايَ فَلَا يَضِلُّ وَلَا يَشْقَى
He said: "Get ye down, both of you,- all together, from the Garden, with enmity one to another: but if, as is sure, there comes to you Guidance from Me, whosoever follows My Guidance, will not lose his way, nor fall into misery.
23:106

They will say: "our Lord! Our misfortune overwhelmed us, and we became a people astray!
