the Messenger of Allah ﷺ said to those sitting with him: “Is one of you incapable of attaining a thousand good deeds?” So a questioner among those seated with him asked him: “How can one of us earn a thousand good deeds?” He said: “(When) one of you recites a hundred Tasbīḥāt a thousand good deeds are written for him, and a thousand evil deeds are wiped away from him.”
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لِجُلَسَائِهِ أَيَعْجِزُ أَحَدُكُمْ أَنْ يَكْسِبَ أَلْفَ حَسَنَةٍ فَسَأَلَهُ سَائِلٌ مِنْ جُلَسَائِهِ كَيْفَ يَكْسِبُ أَحَدُنَا أَلْفَ حَسَنَةٍ قَالَ يُسَبِّحُ أَحَدُكُمْ مِائَةَ تَسْبِيحَةٍ تُكْتَبُ لَهُ أَلْفُ حَسَنَةٍ وَتُحَطُّ عَنْهُ أَلْفُ سَيِّئَةٍ قَالَ هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ
