Assalamu Alaikum, If I recieve my certificate inshallah, am I allowed to teach it to close friends and family and give them a certificate after?

We teach our students to teach family and friends—those that are close—and not to teach publicly, of course. Regarding that which they do not know, they say, "Allah subhanahu wa ta'ala knows best," and they ask those that know. From the greatest means of studying is for students to gather together and select one of them each time to be the teacher (the sheikh) to teach the lesson. Then the next time, another student would become the sheikh, and the third time, the third student, and so on. This serves as a form of revision to deepen one's understanding, as you understand something better when you teach it. It is very effective in studying.
