﴿ قَالَ لَهُۥ مُوسَىٰ هَلْ أَتَّبِعُكَ عَلَىٰٓ أَن تُعَلِّمَنِ مِمَّا عُلِّمْتَ رُشْدًۭا ﴾

“Moses said unto him: "May I follow thee on the understanding that thou wilt impart to me something of that consciousness of what is right which has been imparted to thee?"”

Following the teacher is incumbent on the student In verse 66: هَلْ أَتَّبِعُكَ عَلَىٰ أَن تُعَلِّمَنِ مِمَّا عُلِّمْتَ رُ‌شْدًا ، Sayyidna Musa (علیہ السلام) despite being a prophet and messenger of great resolve, has most reverentially requested al-Khadir (علیہ السلام) if he could follow him to learn his knowledge from him. This tells us that the etiquette of acquiring knowledge is nothing but that the student should show respect for the teacher and follow him (as an individual who is eager to learn) - even if the student happens to be superior to his teacher.
