We can only follow the 4 Madhabs today as opposed to other Madhabs that existed in our history (Dhahiri Madhhab for example) because the 4 well known Madhabs came to us through MASS transmission.

Hanbali
Hanafi
Shafee
Maliki

Only these 4 are acceptable. @DrShadeeElmasry https://t.co/kSIEBwrHMr pic.twitter.com/hiMaM5kPYX
