Hadith 609 وَ بِهَذَا الْإِسْنَادِ عَنْ أَبِی الْحَسَنِ الرِّضَا ع قَالَ: مَا مِنْ مُؤْمِنٍ یَدْعُو لِلْمُؤْمِنِینَ وَ الْمُؤْمِنَاتِ وَ الْمُسْلِمِینَ وَ الْمُسْلِمَاتِ الْأَحْیَاءِ مِنْهُمْ وَ الْأَمْوَاتِ إِلَّا کَتَبَ اللَّهُ لَهُ بِکُلِّ مُؤْمِنٍ وَ مُؤْمِنَهٍ حَسَنَهً مُنْذُ بَعَثَ اللَّهُ آدَمَ إِلَی أَنْ تَقُومَ السَّاعَهُ.
2. And from the previous chain from Abi al-Hassan al-Ridha (a.s.) who said: “No believer supplicates for a living or dead believing men and women and Muslim men and women but that the Almighty Allah writes for him the reward of the good deeds of all believers from Adam (a.s.) till Qiyamat.”
