٤ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ عِيسَى عَنْ أَبِي هَمَّامٍ إِسْمَاعِيلَ بْنِ هَمَّامٍ عَنِ الرِّضَا (عَلَيهِ السَّلام) قَالَ قَالَ عَلِيُّ بْنُ الْحُسَيْنِ (عَلَيهِما السَّلام) إِنَّ الدُّعَاءَ وَالْبَلاءَ لَيَتَرَافَقَانِ إِلَى يَوْمِ الْقِيَامَةِ إِنَّ الدُّعَاءَ لَيَرُدُّ الْبَلاءَ وَقَدْ أُبْرِمَ إِبْرَاماً.
4. Muhammad ibn Yahya has narrated from [Ahmad ibn] Muhammad ibn ‘Isa from abu Hammam Isma’Il ibn Hammam from al-Rida  who has said the following: “Ali ibn al-Husayn  has said, ‘Prayer and pleading before Allah for help, and misfortune are joined together and will remain so until the Day of Judgment. Prayer repeals misfortunes even though it (misfortune) may have already been firmly established.’”
