The verse of tablīgh refers to verse of 5:67 of the Quran, the central religious text of Islam, which readsO Messenger! Convey that which has been sent down unto thee from thy Lord, and if thou dost not, thou wilt not have conveyed His message. And God will protect thee from mankind. Surely God guides not disbelieving people.

The Ghadīr Khumm was a gathering of Muslims to attend a sermon delivered by the Islamic prophet Muhammad on 16 March 632 CE. The gathering is said to have taken place by the ghadir (pool) in the wadi of Khumm, located near the then settlement of al-Juhfa on the path between Mecca and Medina, where Muhammad halted the large caravan of Muslims who had accompanied him in the Farewell Pilgrimage, his only Hajj ritual.
