About Brotherhood

[Dan]

Bismillah

As salam alaikum

A brother is quizzing me on these questions. Could anyone help me out?

1. What are the 3 pillars (Arkaan) of the brotherhood?

2. What are the 3 levels (Darajaat) of brotherhood?'

3. What are the 6 rights (Haqooq) that Muslim brothers have over one another?

Jazakum Allah Khairun.
