Chapter : Concerning the two sermons before the Friday prayer and sitting for a while between the two.

Jabir b. Abdullah reported: I was along with the Apostle of Allah (may peace be upon him) on Friday when a caravan arrived. The people went to it, and none but twelve persons were left behind and I was one of them; and it was on this occasion that this verse was revealed: “And when they see merchandise or sport away to it, and leave thee standing” (lxii. 11).
