﴿ قَالَ ٱهْبِطَا مِنْهَا جَمِيعًۢا ۖ بَعْضُكُمْ لِبَعْضٍ عَدُوٌّۭ ۖ فَإِمَّا يَأْتِيَنَّكُم مِّنِّى هُدًۭى فَمَنِ ٱتَّبَعَ هُدَاىَ فَلَا يَضِلُّ وَلَا يَشْقَىٰ ﴾

“saying: "Down with you all from this [state of innocence, and be henceforth] enemies unto one another! None the less, there shall most certainly come unto you guidance from Me: and he who follows My guidance will not go astray, and neither will he be unhappy.”
