Sayyiduna Ali (may Allah be pleased with him) said: Sayyiduna Umar (may Allah be pleased with him) consulted me regarding the mothers of children (ummhat al-awlad), so both my and Umar's opinion was that they should be set free, and Umar gave judgment on this during his lifetime, and Sayyiduna Uthman (may Allah be pleased with him) also acted upon this during his lifetime. But when I became the caliph, my inclination was towards keeping them as slaves. So Ubaidah (may Allah have mercy on him) said: The collective decision of Umar and Ali (may Allah be pleased with them both) is more beloved to me than the individual opinion of Ali.
