I am a Muslim. We pray towards Mecca, or the Kaba, not at it. We pray to God. Mecca or Kaba, the black rectangle is one of the common things all Muslims have. We all turn in one way as a sign of togetherness and unity. The meteorite there is said to be simply a rock from the Garden of Eden that God sent down to Earth, an oddity bearing no real significance.
Islam gets a bad rep from people who distort it. Suicide is one of the greatest sings in Islam. God gets to decide when you go, not you. In history there have always been those who would subvert religion for their own purposes. We moderate Muslims do not consider people like Osama and the like Muslims, not really.
But to itsda5oh I say: “Really?!?!?”
You think that bombing the holiest site to Muslims is a good idea. There are almost two billion Muslims in the world. The extremes are less than a fraction of one percent. I assure you it would not be in your best interest.
