2ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنِ الْحَسَنِ بْنِ مَحْبُوبٍ عَنْ عَبْدِ الله بْنِ سِنَانٍ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ دُعَاءُ الْمَرْءِ لأخِيهِ بِظَهْرِ الْغَيْبِ يُدِرُّ الرِّزْقَ وَيَدْفَعُ الْمَكْرُوهَ.
2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from al-Hassan ibn Mahbub from ‘Abd Allah ibn Sinan from Abu ‘Abdillah (a.s.) who has said the following: “A man’s prayer for his brother (in belief) in his absence increases his sustenance and repulses misfortune.”
