Certificates of Knowledge and Sincerity- [Reminder for those who say: We only invite those who have graduated!]
Quote from Shaikh Uthaymeen (rahimahullaah): And because of this, even if we you were to find a scholar who is good in various affairs of knowledge but he has no certificate, it will not be possible for him to teach even in high school and this is the reality. And you will find that the one lesser in knowledge than this scholar will be accepted (as a teacher) at a university as long as he has a certificate. http://salaficentre.com/2015/06/the-connection-between-certificates-of-knowledge-and-sincerity-shaikh-uthaymeen-clarifies/
