حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا مَرْوَانُ، وَعَلِيُّ بْنُ مُسْهِرٍ، عَنْ مُوسَى الْجُهَنِيِّ، ح وَحَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، - وَاللَّفْظُ لَهُ - حَدَّثَنَا أَبِي، حَدَّثَنَا مُوسَى الْجُهَنِيُّ، عَنْ مُصْعَبِ بْنِ سَعْدٍ، حَدَّثَنِي أَبِي قَالَ، كُنَّا عِنْدَ رَسُولِ اللَّهِ صلى الله عليه وسلم فَقَالَ " أَيَعْجِزُ أَحَدُكُمْ أَنْ يَكْسِبَ كُلَّ يَوْمٍ أَلْفَ حَسَنَةٍ " . فَسَأَلَهُ سَائِلٌ مِنْ جُلَسَائِهِ كَيْفَ يَكْسِبُ أَحَدُنَا أَلْفَ حَسَنَةٍ قَالَ " يُسَبِّحُ مِائَةَ تَسْبِيحَةٍ فَيُكْتَبُ لَهُ أَلْفُ حَسَنَةٍ أَوْ يُحَطُّ عَنْهُ أَلْفُ خَطِيئَةٍ " .
Mus'ab b. Sa'd reported that his father told him that he had been in the company of Allah's Messenger (ﷺ) that he said: Is one amongst you powerless to get one thousand virtues every day. Amongst those who had been sitting there, one asked: How one amongst us can get one thousand virtues every day? He said: Recite:" Exalted is Allah (He is free from imperfection) one hundred times for (by reciting them) one thousand virtues are recorded (to your credit) and one thousand vices are blotted out.
