[Machine] "If a man supplicates in times of prosperity, and then hardship befalls him, he prays, and the angels say, 'A known voice, forgive him.' But if a man does not supplicate in times of prosperity, and then hardship befalls him, he prays, and the angels say, 'A voice that is not known, and they do not intercede for him.'"  

الزهد لأحمد:١٨١٩حَدَّثَنَا عَبْدُ اللَّهِ قَالَ أُخْبِرْتُ عَنْ سَيَّارٍ حَدَّثَنَا جَعْفَرٌ حَدَّثَنَا ثَابِتٌ عَنْ أَبِي عُثْمَانَ عَنْ سَلْمَانَ قَالَ

إِذَا كَانَ الرَّجُلُ دَعَّاءً فِي السَّرَّاءِ ثُمَّ نَزَلَتْ بِهِ ضَرَّاءُ فَدَعَا قَالَتِ الْمَلَائِكَةُ صَوْتٌ مَعْرُوفٌ اسْتَغْفِرُوا لَهُ وَإِذَا كَانَ الرَّجُلُ لَيْسَ بِدَعَّاءٍ فِي السَّرَّاءِ فَنَزَلَتْ بِهِ ضَرَّاءُ فَدَعَا قَالَتِ الْمَلَائِكَةُ «صَوْتٌ لَيْسَ بِمَعْرُوفٍ وَلَا يَشْفَعُونَ لَهُ»
