Abu Burda reported from his father that the Messenger of Allah,
may Allah bless him and grant him peace, said, "The slave has two rewards
when he carries out Allah's due in worship (or he said that he is excellent
in his worship) and the right of his owner who owns him."
Abu Musa reported that the Messenger of Allah, may Allah bless
him and grant him peace, said, "The slave who is excellent in the worship
of his Lord and fulfils the duties of obedience and counsel which he owes
to his master, has two rewards."
Ibn 'Umar reported that the Messenger of Allah, may Allah bless
him and grant him peace, said, "All of you are shepherds and each of you
is responsible for his flock. The amir of a people is a shepherd and he
is responsible for his flock. A man is the shepherd of the people of his
house and he is responsible for his flock. A man's slave is the shepherd
of his master's property and he is responsible for it. Each of you is a
shepherd and each of you is responsible for his flock."
Narrated Salih ibn Hayy reported that a man said to 'Amir ash-Shu'bi, "Abu
'Amr! We say that when a man frees his umm walad and then marries her,
he is like the one who rides his camel." 'Amir said, "Abu Burda related
to me from his father that the Messenger of Allah, may Allah bless him
and grant him peace,:
'Three have a double reward: one of
the People of the Book who believes in his Prophet and then believes in
Muhammad has two rewards. When a slave carries out the due of Allah and
the due of his master, he has a double reward. And (the third is) a man
who has a slavegirl with whom he has intercourse and teaches her well and
instructs her well and then sets her free and marries her. He has two rewards.'"
