Quran 18:42 from Surah Al-Kahf on Divine Marvels.
وَأُحِيطَ بِثَمَرِهِۦ فَأَصۡبَحَ يُقَلِّبُ كَفَّيۡهِ عَلَىٰ مَآ أَنفَقَ فِيهَا وَهِيَ خَاوِيَةٌ عَلَىٰ عُرُوشِهَا وَيَقُولُ يَٰلَيۡتَنِي لَمۡ أُشۡرِكۡ بِرَبِّيٓ أَحَدٗا
English translation: And were surrounded his fruits so he began twisting his hands over what he (had) spent on it while it (had) collapsed on its trellises and he said Oh! I wish I had not associated I had not associated with my Lord anyone
Transliteration: wa-uhita bithamarihi fa-asbaha yuqallibu kaffayhi ala ma anfaqa fiha wahiya khawiyatun ala urushiha wayaqulu yalaytani lam ush'rik birabbi ahadan
