Treat your slaves with kindness and respect; strive to free your slaves whenever possible; use freedom as an expiation when you have mistreated your slave in any way; show compassion towards those less fortunate than you.

This hadith speaks to the importance of freeing slaves. It was narrated by Zadhan Abl Umar who reported that he came to Ibn 'Umar as he had granted freedom to a slave. He then took hold of a wood or something like it from the earth and said that freedom has no reward equal to it. This was based on what Allah's Messenger said - that if someone slaps their slave or beats them, they should set them free as an expiation for this action. This hadith teaches us the importance of treating our slaves with kindness and respect and not mistreating them in any way. It also shows us how freeing a slave can be seen as an act of great virtue in Islam and how we should strive to do so whenever possible.
