Surah Al-Furqan (The Criterion), Verse 27

وَیَوْمَ یَعَضُّ الظَّالِمُ عَلٰی یَدَیْهِ یَقُوْلُ یٰلَیْتَنِی اتَّخَذْتُ مَعَ الرَّسُوْلِ سَبِیْلًا ۟

Wa Yawma ya'adduz zaalimu 'alaa yadaihi yaqoolu yaa laitanit takhaztu ma'ar Rasooli sabeelaa

“The Day that the wrong-doer will bite at his hands, he will say, "Oh! would that I had taken a (straight) path with the Messenger!”
