اَلْحَسَنُ بْنُ مَحْبُوبٍ عَنْ أَبِي وَلاَّدٍ وَ عَبْدِ اَللَّهِ بْنِ سِنَانٍ جَمِيعاً عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ:« يَنْبَغِي لِأَوْلِيَاءِ اَلْمَيِّتِ مِنْكُمْ أَنْ يُؤْذِنُوا إِخْوَانَ اَلْمَيِّتِ بِمَوْتِهِ فَيَشْهَدُونَ جَنَازَتَهُ وَ يُصَلُّونَ عَلَيْهِ وَ يَسْتَغْفِرُونَ لَهُ فَيُكْتَسَبُ لَهُمُ اَلْأَجْرُ وَ يُكْتَبُ لِلْمَيِّتِ اَلاِسْتِغْفَارُ وَ يَكْتَسِبُ هُوَ اَلْأَجْرَ وَ فِيمَا اِكْتَسَبَ لَهُ مِنَ اَلاِسْتِغْفَارِ».
Al-Hasan ibn Mahbub, from Abi Walad and 'Abdullah ibn Sinan, both from Abu 'Abdillah عليه السلام, who said:
Imam عليه السلام said: "It is proper for the relatives of the deceased among you to inform the brothers (companions) of the deceased about his death, so they may attend his funeral, perform the prayer over him, and seek forgiveness for him. Through this, reward will be earned for them, forgiveness will be written for the deceased, and he too will receive reward from what has been earned for him through their supplications for forgiveness."
