Heretic. There is no need for anymore prophets once the Word became flesh.
Umm, ever hear of John the Revelator???
I suppose God could still send prophets after the birth of his Son, but there is no way that a Christian can believe Mohammed is one.
If you believe Mohammed is a true prophet, then you don’t believe Jesus is God or Son of God, and you are a Muslim.
As for Mo’s great teachings - give alms to the poor, and don’t smother your baby girls in the sand - those are good ones.
Gotta let those baby girls grow up to become nine year old brides - not so good.
