brothers and sisters,

A question arose to me when I started revising back my Islamic subjects for an exam. Then I came across the part where they talk about the sahabahs(r.a.). Their behavior, attitude, contribution to Islam and etc2. So I started thinking, why do we need the Sahabahs as inspiration when we have the prophet Muhammad S.A.W.? Lastly, does the Sahabahs(r.a.) rank more higher than our own parents?
