Teran(IP)- Leader of the Islamic Revolution, Ayatollah Sayyed Ali Khamenei, in a meeting with the participants of the 7th Summit of the General Assembly of the AhlulBayt World Assembly on Saturday morning, said:" Inspired by the Qur'an, the venerable Imam taught everyone to put aside all unreal dividing lines between Islamic societies and for people to accept only one dividing line. That dividing line is the demarcation that marks the border between the Islamic world and the world of unbelief and arrogance."
