You ignorance is proving to be a curse for you. The whole world knows that al-i-Sheikh (that a crackhead idiot would call it Wahabism) holds only the Qadha (ministry of justice?) in Saudi Arabia while Al-i-Saud runs the country (administration, ministries, foreign policy, etc.) Even most of the imams in Haramain-Sharifain are not from al-i-Sheikh. You are offering an article published on some personal website as an evidence that Saudi government considers Iranian Shias as kafir. You need to see a highly qualified mental doctor, dude.
BTW, Saudi government allows/welcomes Irani Shia haj pilgrims. Can they allow kuffar to perform haj at any cost? Ponder on this if you have a bit of working brain.
