The Occasion of Revelation A tradition says that this Surah was revealed after the occurrence of the war/ that-us-salasil/. the description is as follows: In the eighth year A.H. the Prophet (S) of Islam was informed that twelve thousand strong had gathered in Yabis to make a sudden and very heavy attack on Medina to kill the Muslims, the holy Prophet and Ali (as) as well. Upon receiving the news of this gathering of hostile forces.
The holy Prophet (S) sent a group of the Muslim followers to them under the command of some of his companions, but they returned without gaining any positive result. Finally, he sent Hazrat Ali (as) with a great number of the emigrants (Muhajirs), and the helpers, under his command, to meet them. They marched by night and kept themselves concealed by day and thus, they reached the enemy.
Surrounding the enemy's forces, Hazrat Ali (as) offered them (to follow the religion of) Islam at first, but they did not accept it. Then, the Muslims attacked them in the early hours of dawn when it was still dark and won an easy victory. Most of the enemy's men were killed, and those who remained, Ali (as) put them in chains and took them, with their collective properties, to the holy Prophet (S) in Medina. Before the Muslim forces reached Medina, this Surah was revealed.
The holy Prophet (S) came out early that very morning and recited this Surah in prayer.
