In Jumadi-ul-Ula 2 AH, the Holy Prophet (sa) assembled a party of eight Muhajireen under the command of Hazrat Sa‘d bin Abi Waqas (ra) and sent them to Kharrar to obtain intelligence about the Quraish. Kharrar is an area in the Hijaz, located near Ju‘fah. They reached there but did not confront the enemy.
