Verses 18:69-70

قَالَ سَتَجِدُنِىٓ إِن شَآءَ ٱللَّهُ صَابِرًا وَلَآ أَعْصِى لَكَ أَمْرًا

قَالَ فَإِنِ ٱتَّبَعْتَنِى فَلَا تَسْـَٔلْنِى عَن شَىْءٍ حَتَّىٰٓ أُحْدِثَ لَكَ مِنْهُ ذِكْرًا

“He said: ‘You will find me, God willing, patient, and I will not disobey any command of yours.’ He said: ‘If you follow me, then do not ask me about anything until I mention it to you.’”
