In 882, Muhammad ibn Lubb, who, like his father Lubb ibn Musa before him, previously had always had good relations with the Christian kingdoms to the north, joined in a coalition with the forces of the Córdoban Emir Muhammad I of Córdoba. The emir, as a gesture of good will, sent his son, Al-Mundhir of Córdoba to join ibn Lubb on raids along the Ebro River. Muhammad ibn Lubb made his way from Zaragoza along the Ebro and devastated the valleys he passed through in La Rioja which at the time belonged to the King of Zaragoza, Isma'el ibn Musa, and the King of Tudela, Fortun ibn Musa, both of whom were uncles of Muhammad ibn Lubb.
