[Machine] "Four things are given to a man after his death: one-third of his wealth if he had it before that and was obedient to Allah, righteous children who pray for him after his death, good deeds that the man practiced and are carried out after his death, and intercession if a hundred people intercede for him."  

الدارمي:٥٣٤أَخْبَرَنَا عَمْرُو بْنُ عَاصِمٍ حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ عَنْ عَاصِمٍ عَنِ الشَّعْبِيِّ أَنَّ ابْنَ مَسْعُودٍ قَالَ

«أَرْبَعٌ يُعْطَاهَا الرَّجُلُ بَعْدَ مَوْتِهِ ثُلُثُ مَالِهِ إِذَا كَانَ فِيهِ قَبْلَ ذَلِكَ لِلَّهِ مُطِيعًا وَالْوَلَدُ الصَّالِحُ يَدْعُو لَهُ مِنْ بَعْدِ مَوْتِهِ وَالسُّنَّةُ الْحَسَنَةُ يَسُنُّهَا الرَّجُلُ فَيُعْمَلُ بِهَا بَعْدَ مَوْتِهِ وَالْمِائَةُ إِذَا شَفَعُوا لِلرَّجُلِ شُفِّعُوا فِيهِ»
