[Machine] We sent the Messenger of Allah ﷺ on a military expedition, and he mentioned a hadith. Then I said, "O Messenger of Allah, command me with something that Allah will benefit me with." He said, "Observe fasting, for there is nothing equal to it." Abu Umamah and his wife and servant used to always be found fasting. When smoke was seen emerging from their house during the day, it was said that they were hosting guests. Then I went to the Messenger of Allah ﷺ and said, "O Messenger of Allah, you have commanded me with something that I hope Allah has blessed me with. So command me with something else." He said, "Know that whenever you prostrate to Allah, He elevates you in rank, writes a good deed for you, and removes a bad deed from you." This was narrated by Mahdi ibn Maymun from Muhammad ibn Abi Ya'qub, and Shu'bah narrated it from Muhammad ibn Abi Ya'qub, who narrated it from Abu Nasr al-Hilali, who narrated it from Raja bin Haywah, who narrated it from Abu Umamah.  

بَعَثَنَا رَسُولُ اللهِ ﷺ فِي سَرِيَّةٍ فَذَكَرَ الْحَدِيثَ ثُمَّ قُلْتُ يَا رَسُولَ اللهِ مُرْنِي بِأَمْرٍ يَنْفَعُنِي اللهُ بِهِ قَالَ عَلَيْكَ بِالصِّيَامِ فَإِنَّهُ لَا مِثْلَ لَهُ قَالَ فَكَانَ أَبُو أُمَامَةَ لَا يُلْقَى إِلَّا صَائِمًا هُوَ وَامْرَأَتُهُ وَخَادِمُهُ فَإِذَا رُئِيَ فِي دَارِهِ دُخَانٌ بِالنَّهَارِ قِيلَ اعْتَرَاهُمْ ضَيْفٌ ثُمَّ أَتَيْتُ رَسُولَ اللهِ ﷺ فَقُلْتُ يَا رَسُولَ اللهِ إِنَّكَ أَمَرْتَنِي بِأَمْرٍ أَرْجُو اللهَ أَنْ يَكُونَ قَدْ بَارَكَ اللهُ لِي فِيهِ فَمُرْنِي بِأَمْرٍ قَالَ اعْلَمْ أَنَّكَ لَا تَسْجُدُ لِلَّهِ سَجْدَةً إِلَّا رَفَعَكَ اللهُ بِهَا دَرَجَةً وَكَتَبَ لَكَ بِهَا حَسَنَةً وَحَطَّ عَنْكَ بِهَا سَيِّئَةً تَابَعَهُ مَهْدِيُّ بْنُ مَيْمُونٍ عَنْ مُحَمَّدِ بْنِ أَبِي يَعْقُوبَ وَرَوَاهُ شُعْبَةُ عَنْ مُحَمَّدِ بْنِ أَبِي يَعْقُوبَ عَنْ أَبِي نَصْرٍ الْهِلَالِيِّ عَنْ رَجَاءِ بْنِ حَيْوَةَ عَنْ أَبِي أُمَامَةَ
