Re: Are today’s muslims, yesterday’s Bani Israeel?
The message of Muhammad (s.a.w.) is the same message as those of previous prophets. They all professed the worship of One God without joining any partners with Him. So the point about Isa (a.s.) not knowing anything about Islam is misleading at best. Tauheed has been the foundation of all Prophets that we have been told of from Nuh (a.s.) to Isa (a.s.).
The rest of what you said, I prefer not to reply because I would rather move forward than go in circles.
PS: Thanks for clarifying what you meant. I was hoping instead for actual proof. Perhaps we can all learn to make it clear when something is an opinion rather than fact, for the lack of evidence to back it up later.
