Abu Umama said, "The Prophet, may Allah bless him and grant himpeace, came with two slaves and gave one of them to 'Ali and said, 'Donot beat him. I have forbidden beating the people of the prayer and I sawhim praying before we came.' He gave Abu Dharr a slave and said, "I recommendthat you treat him well,' so Abu Dharr set him free. He said, 'What haveyou done?' He replied, 'You commanded me to treat him well, so I set himfree.'"
