١ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ أَبِي سَعِيدٍ الْقَمَّاطِ عَنِ الْمُفَضَّلِ قَالَ قُلْتُ لأبِي عَبْدِ الله (عَلَيهِ السَّلام) جُعِلْتُ فِدَاكَ عَلِّمْنِي دُعَاءً جَامِعاً فَقَالَ لِيَ احْمَدِ الله فَإِنَّهُ لا يَبْقَى أَحَدٌ يُصَلِّي إِلا دَعَا لَكَ يَقُولُ سَمِعَ الله لِمَنْ حَمِدَهُ.
1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from abu Sa’Id al-Qammat from al-Mufaddal who has said the following: “Once I said to Abu ‘Abdillah  ‘May Allah keep my soul in service for your cause, teach me a comperehensive prayer.’ The Imam said to me, ‘Praise Allah; everyone who performs prayer prays for you saying, “Allah listens to (answers the prayers of) those who praise Him” (a reference to the meaning of the phrase said after Ruku ’ in a prayer).’”
