Abu Sufyan gathered 200 mounted men, took the eastern road through the Nejd and secretly arrived by night, at the settlement of Banu Nadir, a Jewish tribe.
Abu Sufyan along with another leader of the Banu Nadir tribe of Jews, Sallam ibn Mishkam, conspired to attack Madinah but they were unsuccessful.
At night, Abu Sufyan took his men to the Urayd corn fields, a place about two or three miles to the north-east of Medina.
The Muslims managed to capture some of the sawiq (a type of flour) thrown away by the Quraysh men, who did so to lighten their burden and flee.
