Narrated Abu Huraira RA: A man came to Allah's Messenger (peace be upon him) and said, "O Allah's Messenger (peace be upon him)! Who is more entitled to be treated with the best companionship by me?" The Prophet (peace be upon him) said, "Your mother." The man said. "Who is next?" The Prophet said, "Your mother." The man further said, "Who is next?" The Prophet (peace be upon him) said, "Your mother." The man asked for the fourth time, "Who is next?" The Prophet (peace be upon him) said, "Your father. " (Bukhari - Vol. 8, Book 73, Hadith 2)
