General Behavior (Kitab Al-Adab)

Dawud :: Book 41 : Hadith 5121

Narrated Bakr ibn al-Harith al-Anmari:

Bakr went to the Prophet (peace_be_upon_him) and said: Apostle of Allah! to whom should I show kindness? He said: Your mother, your sister, your brother and the slave whom you set free and who is your relative, a due binding (on you), and a tie of relationship which should be joined.
