Quran 20:94 from Surah Taa-Haa on Divine Marvels.
قَالَ يَبۡنَؤُمَّ لَا تَأۡخُذۡ بِلِحۡيَتِي وَلَا بِرَأۡسِيٓۖ إِنِّي خَشِيتُ أَن تَقُولَ فَرَّقۡتَ بَيۡنَ بَنِيٓ إِسۡرَٰٓءِيلَ وَلَمۡ تَرۡقُبۡ قَوۡلِي
English translation: He said O son of my mother (Do) not seize (me) by my beard and not by my head Indeed, I [I] feared that you would say You caused division between (the) Children of Israel (the) Children of Israel and not you respect my word
Transliteration: qala yabna-umma la takhudh bilih'yati wala birasi inni khashitu an taqula farraqta bayna bani is'raila walam tarqub qawli
