﴿ وَيَٰٓـَٔادَمُ ٱسْكُنْ أَنتَ وَزَوْجُكَ ٱلْجَنَّةَ فَكُلَا مِنْ حَيْثُ شِئْتُمَا وَلَا تَقْرَبَا هَٰذِهِ ٱلشَّجَرَةَ فَتَكُونَا مِنَ ٱلظَّٰلِمِينَ ﴾

“And [as for thee], O Adam', dwell thou and thy wife in this garden, and eat, both of you, whatever you may wish; but do not approach this one tree, lest you become evildoers!"”
