Abu Hurayra reported: "A man came to the Prophet (ﷺ) of Allah, may Allah bless him and grant him peace, and asked, 'What do you command me to do?' He replied, 'Be dutiful towards your mother.' Then he asked him the same question again and he replied, 'Be dutiful towards your mother.' He repeated it yet again and the Prophet (ﷺ) replied, 'Be dutiful towards your mother.' Then he put the question a fourth time and the Prophet (ﷺ) said, 'Be dutiful towards your father.'"
