حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، قَالَ: حَدَّثَنَا وُهَيْبُ بْنُ خَالِدٍ، عَنِ ابْنِ شُبْرُمَةَ قَالَ: سَمِعْتُ أَبَا زُرْعَةَ، عَنْ أَبِي هُرَيْرَةَ قَالَ: قِيلَ: يَا رَسُولَ اللهِ صلى الله عليه وسلم، مَنْ أَبَرُّ؟ قَالَ: أُمَّكَ، قَالَ: ثُمَّ مَنْ؟ قَالَ: أُمَّكَ، قَالَ: ثُمَّ مَنْ؟ قَالَ: أُمَّكَ، قَالَ: ثُمَّ مَنْ؟ قَالَ: أَبَاكَ.
Abu Hurayra said, "The Prophet was asked, 'Messenger of Allah, to whom should I be dutiful?' 'Your mother,' he replied. He was asked, 'Then whom?' 'Your mother,' he replied. He was asked, 'Then whom?' 'Your mother,' he replied. He was asked, 'Then whom?' He replied, 'Your father.'"
