Zealotry, the increasing radicalism and the lie that is Islam, is the cause of this human tragedy. Right from the beginning of Islam and the writing of the Koran, truth was stood on it’s head, replaced with the lies of plagiarism of the Jewish Torah and the Old Testament of the Bible to make up the Koran.
To further buttress the lies, the jihad and brutality of forced conversions made Islam a religion which kills the mind, does not allow free expression or reflection but docile and brutal brain washing.
This is why you see Islamists the world over, killing, pillaging, raping, looting, burning, destroying and generally causing chaos and unrest everywhere!
Why would one need to travel to a foreign nation for pilgrimage or speak a foreign language before Allah can hear or answer his/her prayers. This is part of the institutionalized lies and brain washing perpetuated by the Saudi royal family to keep people indentured to Islam.
Religion is a spiritual worship of God which is a personal relationship with God and not servitude to a nation. This mass hysteria and mindless pilgrimage, will continue to cause untold deaths of adherents, until they learn that God hears your prayers wherever you are and in whatever language you speak.
