The Quran says Jesus will come back...and RENOUNCE the Gospel. It also claims that Abraham and Ishmael built the Kaaba (in Mecca), when Abraham existed thousands of years earlier and cast Ishmael out and never saw him again. It portrays the "Angel Gabriel" as refusing to come into Muhammed's home while he has dogs...so Mohammed KILLS his dogs...which is the basis for Muslims' sick hatred of dogs (Somali taxi drivers sued for refusing seeing eye dogs, horrible videos of Iranians poising dogs en masse, etc)
MY personal theory as to why muslims hate dogs and don’t keep them around, is because 5 times a day, when the guy goes up in the tower and starts his wailing, any dog within earshot will start howling and howl right along with him. They can’t have THAT. So dogs must go.
