What are the etiquettes of a student of knowledge in the presence of his shaykh, and do they include not leaning, not extending one's leg, and not speaking?

Question:
He says: Honorable Shaykh, may Allah grant you success. He says: I read in some books on the etiquettes of seeking knowledge that the student should sit in the presence of his shaykh as Jibril sat with the Prophet (peace and blessings be upon him), and that he should not lean, not extend his leg in the shaykh's presence, and not speak in the shaykh's presence. It is said that whoever speaks in the shaykh's presence will not succeed. He says: In this regard, he will not succeed. Yes, are all of these correct etiquettes without any exaggeration?

Answer:
Yes, among the etiquettes of a student of knowledge in the presence of his shaykh is that he respects him first of all; he respects the shaykh, holds him in high esteem, behaves with good manners toward him, asks questions well, listens, and receives from his shaykh with good manners, without fidgeting, and without sitting in the manner of an arrogant person. He sits in the manner of a student with his teacher. There are books written on the etiquettes of the student of knowledge, including what al-Hafiz al-Khatib al-Baghdadi wrote on the etiquettes of the scholar and the student, and what Imam Ibn 'Abd al-Barr and others wrote on this topic. Yes.
