Al-Adab al-Mufrad 94
حَدَّثَنَا ابْنُ مَخْلَدٍ، عَنْ عِيسَى بْنِ يُونُسَ، عَنِ الْوَصَّافِيِّ، عَنْ مُحَارِبِ بْنِ دِثَارٍ، عَنِ ابْنِ عُمَرَ قَالَ: إِنَّمَا سَمَّاهُمُ اللَّهُ أَبْرَارًا، لأَنَّهُمْ بَرُّوا الْآبَاءَ وَالأَبْنَاءَ، كَمَا أَنَّ لِوَالِدِكَ عَلَيْكَ حَقًّا، كَذَلِكَ لِوَلَدِكَ عَلَيْكَ حَقٌّ.
Ibn 'Umar said, "Allah has called them the 'dutiful' (al-Abrar) because they are dutiful (birr) to their parents and children. Just as you have a duty which you owe your parent, so you have a duty which you owe your child."
