The Book, Quran
الخصال لي، الأمالي للصدوق أَبِي عَنْ سَعْدٍ عَنِ الْيَقْطِينِيِّ عَنْ مُحَمَّدِ بْنِ شُعَيْبٍ عَنِ الْهَيْثَمِ بْنِ أَبِي كَهْمَسٍ عَنِ الصَّادِقِ ع قَالَ: سِتُّ خِصَالٍ يَنْتَفِعُ بِهَا الْمُؤْمِنُ مِنْ بَعْدِ مَوْتِهِ وَلَدٌ صَالِحٌ يَسْتَغْفِرُ لَهُ وَ مُصْحَفٌ يُقْرَأُ مِنْهُ وَ قَلِيبٌ يَحْفِرُهُ وَ غَرْسٌ يَغْرِسُهُ وَ صَدَقَةُ مَاءٍ يُجْرِيهِ وَ سُنَّةٌ حَسَنَةٌ يُؤْخَذُ بِهَا بَعْدَهُ
(The book) ‘Al Khisaal’, (and) ‘Al Amaali’ of Al Sadouq – My father, from Sa’ad, from Al Yaqteeny, from Muhammad Bin Shueyb, from Al Heysam Bin Abu Kahmas,
From Al-Sadiq-asws having said: ‘There are six characteristics the Momin can benefit from after his death – a righteous son’s seeking Forgiveness for him, and a Quran being read from, and a well he had dug, and a plant he had planted, and charity of water he caused to flow, and a good conduct (tradition) he had left behind as his legacy’.[1]
إِنَّ هَٰذَا لَفِي الصُّحُفِ الْأُولَىٰ {18}
Surely, this is (also written) in the former Parchments [87:18]
صُحُفِ إِبْرَاهِيمَ وَمُوسَىٰ {19}
The Parchments of Ibrahim and Musa [87:19]
