Bidaat Of Quraysh
Please refer from 34:25 to 38:50 https://youtu.be/7Wp7syihMus?t=2065
Just like those Bidahs were identifiable similarly Bidahs in today’s time are also identifiable, but with more accuracy. As can be witnessed with regards to Hajj, Prophet Muhammad (sws) did the Hajj as was prescribed without any Bidah.
No worries, that was a joke anyway.
