With regards to the student of knowledge honouring his teacher and the consequences of not doing so, the Noble Shaykh Muhammad ibn Saalih al Uthaymeen rahimahullaah stated:
And I advise you likewise to honour your teachers because the teacher – if he is a teacher in the true sense, one who sincerely advises – has two virtues over the students:
· The first virtue – that of teaching (them)
· The second virtue – that of giving guidance and of correctly nurturing
So the one who is a teacher in reality disseminates knowledge amongst the students and loves that his guidance and his direction be disseminated. So if he establishes this then he becomes one who is deserving of being honoured and respected.
And know that if you honour the teacher in the way that is befitting then you will take benefit from this teacher.
As for if he perceives that you attach little importance to him, then you will lose out on him and lose out on his guidance to you.
