Al-Kahf - 18:76

قَالَ إِن سَأَلْتُكَ عَن شَيْءٍ بَعْدَهَا فَلَا تُصَاحِبْنِي قَدْ بَلَغْتَ مِن لَّدُنِّي عُذْرًا
[18:76]
He said: If I ask you about anything after this, keep me not in your company; indeed you shall have (then) found an excuse in my case.
(Moses) said: "If ever I ask thee about anything after this, keep me not in thy company: then wouldst thou have received (full) excuse from my side."
(Moses) said: If I ask thee after this concerning aught, keep not company with me. Thou hast received an excuse from me.
