Hadith 6

حَدَّثَنَا بِشْرُ بْنُ مُحَمَّدٍ، قَالَ‏:‏ أَخْبَرَنَا عَبْدُ اللّٰهِ، قَالَ‏:‏ أَخْبَرَنَا يَحْيَى بْنُ أَيُّوبَ، قَالَ‏:‏ حَدَّثَنَا أَبُو زُرْعَةَ، عَنْ أَبِي هُرَيْرَةَ، أَتَى رَجُلٌ نَبِيَّ اللّٰهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ‏:‏ مَا تَأْمُرُنِي‏؟‏ فَقَالَ‏:‏ ”بِرَّ أُمَّكَ“، ثُمَّ عَادَ، فَقَالَ‏:‏ ”بِرَّ أُمَّكَ“، ثُمَّ عَادَ الرَّابِعَةَ، فَقَالَ‏:‏ ”بِرَّ أُمَّكَ“، ثُمَّ عَادَ الْخَامِسَةَ، فَقَالَ‏:‏ ”بِرَّ أَبَاكَ‏.‏“
Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that a man came to the Prophet of Allah (peace and blessings of Allah be upon him) and said: "What do you command me?" The Prophet (peace be upon him) said: "Show kindness to your mother." He asked the same question again. The Prophet (peace be upon him) said: "Show kindness to your mother." He repeated the question. The Prophet (peace be upon him) said: "Show kindness to your mother." Then he asked a fourth time, and the Prophet (peace be upon him) said: "Show kindness to your mother." He asked a fifth time, and the Prophet (peace be upon him) said: "Show kindness to your father."
