ذِكْرُ الْبَيَانِ بِأَنَّ اتِّخَاذَ الْأَحْبَاسِ فِي سَبِيلِ اللَّهِ مِنْ خَيْرِ مَا يَخْلُفُ الْمَرْءُ بَعْدَهُ

[Machine] I heard the Prophetﷺ saying, "The best thing that remains for a person after his death are three: a righteous child who supplicates for him, a continuous charity whose reward reaches him, and a beneficial knowledge that is acted upon after him."  

ابن حبّان:٤٩٠٢ – أَخْبَرَنَا أَبُو عَرُوبَةَ قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ وَهْبِ بْنِ أَبِي كَرِيمَةَ قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ سَلَمَةَ عَنْ أَبِي عَبْدِ الرَّحِيمِ قَالَ حَدَّثَنِي زَيْدُ بْنُ أَبِي أُنَيْسَةَ عَنْ فُلَيْحِ بْنِ سُلَيْمَانَ عَنْ زَيْدِ بْنِ أَسْلَمَ عَنْ عَبْدِ اللَّهِ بْنِ أَبِي قَتَادَةَ عَنْ أَبِيهِ قَالَ

سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ «خَيْرُ مَا يَخْلُفُ الْمَرْءُ بَعْدَ مَوْتِهِ ثَلَاثٌ وَلَدٌ صَالِحٌ يَدْعُو لَهُ وَصَدَقَةٌ تَجْرِي يَبْلُغُهُ أَجْرُهَا وَعَمَلٌ يُعْمَلُ بِهِ مِنْ بَعْدِهِ»

[Machine] I heard the Messenger of Allah, peace be upon him, saying, "The best things a person leaves behind after his death are three: a righteous child who prays for him, ongoing charity from which he continues to receive reward, and beneficial knowledge that others benefit from after him."  

ابن حبّان:٩٣ – أَخْبَرَنَا الْحَسَنُ بْنُ سُفْيَانَ قَالَ حَدَّثَنَا إِسْمَاعِيلُ بْنُ عُبَيْدِ بْنِ أَبِي كَرِيمَةَ هُوَ الْحَرَّانِيُّ قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ سَلَمَةَ عَنْ أَبِي عَبْدِ الرَّحِيمِ عَنْ زَيْدِ بْنِ أَبِي أُنَيْسَةَ عَنْ زَيْدِ بْنِ أَسْلَمَ عَنْ عَبْدِ اللَّهِ بْنِ أَبِي قَتَادَةَ عَنْ أَبِيهِ قَالَ

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «خَيْرُ مَا يَخْلُفُ الرَّجُلَ بَعْدَهُ ثَلَاثٌ وَلَدٌ صَالِحٌ يَدْعُو لَهُ وَصَدَقَةٌ تَجْرِي يَبْلُغُهُ أَجْرُهَا وَعِلْمٌ يُنْتَفَعُ بِهِ مِنْ بَعْدِهِ»
