Hadith: Arabic Text followed by English Translation.
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 ” .”
رواه مسلم ٢٦٩٨
‘Mus‘ab ibn Sa‘d ibn Abi Waqqaas said: My father told me: We were with the Messenger of Allah (blessings and peace of Allah be upon him) and he said:
“Is it too difficult for any one of you to earn one thousand hasanahs (good deeds) every day?”
One of those who were sitting with him asked him:
How can one of us earn one thousand hasanahs?He said:
“If he says one hundred tasbeehs (saying ‘Subhanallah’), one thousand hasanahs will be recorded for him, or one thousand bad deeds will be erased for him.”
