O pilgrims of the Arbaeen of Imam Hussein (peace be upon him)! Be aware that what a great work is done by you and know this fact that you create a multi-million population of Arbaeen pilgrims which brings about plenty of bounties and blessings. Undoubtedly, this is the very beginning and in the not too far future, the world will be influenced greatly by the mission and school of Imam Hussein peace be upon him and his pilgrims and visitors, and in no time, the light of false religions as well as none divine schools will be silenced by the storm of faith in Imam Hussein (peace be upon him), and who knows maybe the same Arbaeen of Imam Hussein paves the way for the reappearance of Imam of the time (may Allah Hasten his reappearance) and brings about the establishment of universal justice and acceptance of the school of Imam Hussein (peace be upon him). Allah willing.
