Congratulation to the 12th Imam and the Imam of our time, Imam Mahdi, and all of his followers for Eid al-Ghadir.
May Allah hasten the reappearance of him and bless him and all of his followers.
Ghadir Khumm is a place between the two cities of Mecca and Medina where the holy prophet Muhammad (PBUH) stopped while he was returning from his last Hajj pilgrimage and waited for three days till all the people gathered. Then, he held up Imam Ali’s hand and said:
“for whoever I am his leader, this Ali is his leader.”
The Prophet continued about Imam Ali:
“O’ God, love those who loves him, and be hostile to those who is hostile to him.”
