Al Kahf

قَالَ فإِنِ اتَّبَعْتَنِي فَلاَ تَسْأَلْنِي عَن شَيْءٍ حَتَّي اُحْدِثَ لَكَ مِنْهُ ذِكْراً

He warned him that if he wished to follow him, he had to be absolutely silent and would not ask him concerning any thing until, on its time, Khidr might tell him about it. The verse says:

Moses (as) undertook this promise again and proceeded companying ‘that great Teacher’.
