WTF is Kaaba and the black stone?

If you look at this image you may think is a fucking toilet or something but no, it isnt. In fact is a stone from heavem (al-Hajar-el-Aswad), from paradise that Allah sent to earth. Yes, it is from our view, a fucking meteor, not from motherfucking Allah. That is why all muslims pray to Mecca, the holy city of Islam. By the way there was a beheading in holy city some days ago. It has to be a holy fucking city.

One time I asked a muslim, a sunni one, if by any means, the stone is destroyed, he said, there will be a war. 

And if USA bombed the stone, we would kill them. 

Can´t god sent another one?

Silence.

It is so fucking holy that god, a lazy fuck, can´t send other.

And you are always saying that christians pray in front of a cross, you muslims pray in direction of a fucking stone.

This is the kaaba, the building!
