Narrated Jabir bin `Abdullah:
A caravan of merchandise arrived at Medina on a Friday while we were with the Prophet (ﷺ) All the people left (the Prophet (ﷺ) and headed for the caravan) except twelve persons. Then Allah revealed:-- 'But when they see some bargain or some amusement they disperse headlong to it.' ..(62.11)
