Surat Al-Kahf (The Cave) - الكهف

وَأُحِيطَ بِثَمَرِهِۦ فَأَصْبَحَ يُقَلِّبُ كَفَّيْهِ عَلَىٰ مَآ أَنفَقَ فِيهَا وَهِىَ خَاوِيَةٌ عَلَىٰ عُرُوشِهَا وَيَقُولُ يَٰلَيْتَنِى لَمْ أُشْرِكْ بِرَبِّىٓ أَحَدًا ﴿٤٢﴾

And his wealth was destroyed; so he began to wring his hands for what he had spent on it, while it lay, having fallen down upon its roofs, and he said: Ah me! would that I had not associated anyone with my Lord.
