The prophecies concerning this Mahdi are uncomfortably close to those in the Bible re Christ.
That is because Islam is a false religion originated by a false prophet that we were warned about in the bible.
That's because it was plagerized from the bible by Mohammed. He apparently forgot to read the last paragraph in the book of revelation. The one says that says essentially that anyone that adds to or subtracts from the prophecies contained in this book is going to catch hell.
