Can anyone prove madrassas from Qur'an and Sunnah?
The tariqah is simply a means. A person can be part of a tariqah or he may not. Similarly, a madrassa is a means to an end. A person can attend a madrassa or study directly under a scholar to gain knowledge. It all depends on what is most effective for a person.
But the deobandi scholars told me that the tariaqa is a line that goes back to the prophet? And they also said the tariqahs are named after man from like 400-500 years ago. And they said those men started the tariqahs. So how does it go back to the prophet? It just doesn't make sense to me.
