قَالَ يَبْنَؤُمَّ لَا تَأْخُذْ بِلِحْيَتِى وَلَا بِرَأْسِىٓ ۖ إِنِّى خَشِيتُ أَن تَقُولَ فَرَّقْتَ بَيْنَ بَنِىٓ إِسْرَٰٓءِيلَ وَلَمْ تَرْقُبْ قَوْلِى ۝٩٤

20:94 He said: O son of my mother! Clutch not my beard nor my head! I feared lest thou shouldst say: Thou hast caused division among the Children of Israel, and hast not waited for my word.
