Mukhtasar Muslim

It is narrated from Sayyiduna Jabir bin Abdullah, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, used to deliver the sermon standing on the day of Jumu'ah. So once, a caravan came from Syria (bringing grain), and people rushed towards it, leaving only twelve men with the Prophet, peace and blessings be upon him. Upon this, the verse was revealed which is in Surah Al-Jumu'ah: "When they see a trade or amusement, they rush towards it and leave you standing..." the entire verse.
