Reciting "Subhanallah (Hallowed be Allah)" Is Rewarded Two-Fold

 عَنْ مُصْعَبِ بْنِ سَعْدٍ حَدَّثَنِي أَبِي قَالَ كُنَّا عِنْدَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ 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 (pbuh) that he said:

"Is one amongst you powerless to obtain one thousand virtues every day?" 

Amongst those who had been sitting there, one asked, "How can one amongst us obtain one thousand virtues every day?" 

He said, "Recite: 'Subhanallah (Hallowed be Allah)' one hundred times, for (by reciting it) one thousand virtues are recorded and one thousand vices are blotted out.

عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ مَنْ قَالَ سُبْحَانَ اللَّهِ وَبِحَمْدِهِ فِي يَوْمٍ مِائَةَ مَرَّةٍ حُطَّتْ خَطَايَاهُ وَإِنْ كَانَتْ مِثْلَ زَبَدِ الْبَحْرِ

Narrated Abu Huraira: Allah's Messenger (pbuh) said, "Whoever says 'Subhanallah wa bihamdih (Hallowed be Allah, and all praise is for Allah' one hundred times a day, he will be forgiven of all his sins even if they were as much as the foam of the sea."
