(3) بَابُ بِرِّ الأَبِ
Abu Hurayra reported:
"A man came to the Prophet of Allah, may Allah blesshim 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 againand he replied, 'Be dutiful towards your mother.' He repeated it yet againand the Prophet replied, 'Be dutiful towards your mother.' Then he put the question a fourth time and the Prophet said, 'Be dutiful towardsyour father.'"
