Arabic hadith text
حَدَّثَنِي أَبُو الطَّاهِرِ، أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ، أَخْبَرَنِي حَيْوَةُ بْنُ شُرَيْحٍ، عَنِ ابْنِ، الْهَادِ عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏أَبَرُّ الْبِرِّ أَنْ يَصِلَ الرَّجُلُ وُدَّ أَبِيهِ ‏"
