وَأُحِيطَ بِثَمَرِهِۦ فَأَصْبَحَ يُقَلِّبُ كَفَّيْهِ عَلَىٰ مَآ أَنفَقَ فِيهَا وَهِىَ خَاوِيَةٌ عَلَىٰ عُرُوشِهَا وَيَقُولُ يَٰلَيْتَنِى لَمْ أُشْرِكْ بِرَبِّىٓ أَحَدًۭا
And his fruit was beset (with destruction). Then began he to wring his hands for all that he had spent upon it, when (now) it was all ruined on its trellises, and to say: Would that I had ascribed no partner to my Lord!
