A common Mormon testimony	A common Muslim testimony
I bear you my testimony that I know the Book of Mormon is true, I know that Joseph Smith is a true Prophet of God and I know that the Church is the only true church	I bear witness that there is no god but Allah, and I bear witness that Mohammed is the servant and Messenger of Allah (the "Shahada")
