It is narrated from Hazrat Abu Salamah (may Allah be pleased with him) that once the Holy Prophet (peace and blessings be upon him) said three times: I enjoin every person to treat his mother well. Then he said twice: I enjoin every person to treat his father well. And I enjoin every person to treat his servant well, even if he receives any harm from these individuals. The previous hadith is also narrated through this second chain of transmission.
