Muhammad bin al-Harith (may Allah have mercy on him) narrates with his chain that the Prophet (peace and blessings be upon him) said: "There is no pre-emption for a minor, nor for an absent person; and when a partner precedes his partner in pre-emption, there is no pre-emption; and pre-emption is like a knot (being untied)."
