Sunan of Abu Dawood Book 2, Hadith 864

حَدَّثَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا إِسْمَاعِيلُ، حَدَّثَنَا يُونُسُ، عَنِ الْحَسَنِ، عَنْ أَنَسِ بْنِ حَكِيمٍ الضَّبِّيِّ، قَالَ خَافَ مِنْ زِيَادٍ أَوِ ابْنِ زِيَادٍ فَأَتَى الْمَدِينَةَ فَلَقِيَ أَبَا هُرَيْرَةَ قَالَ فَنَسَبَنِي فَانْتَسَبْتُ لَهُ فَقَالَ يَا فَتَى أَلاَ أُحَدِّثُكَ حَدِيثًا قَالَ قُلْتُ بَلَى رَحِمَكَ اللَّهُ ‏.‏ قَالَ يُونُسُ أَحْسِبُهُ ذَكَرَهُ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏ "‏ إِنَّ أَوَّلَ مَا يُحَاسَبُ النَّاسُ بِهِ يَوْمَ الْقِيَامَةِ مِنْ أَعْمَالِهِمُ الصَّلاَةُ قَالَ يَقُولُ رَبُّنَا جَلَّ وَعَزَّ لِمَلاَئِكَتِهِ وَهُوَ أَعْلَمُ انْظُرُوا فِي صَلاَةِ عَبْدِي أَتَمَّهَا أَمْ نَقَصَهَا فَإِنْ كَانَتْ تَامَّةً كُتِبَتْ لَهُ تَامَّةً وَإِنْ كَانَ انْتَقَصَ مِنْهَا شَيْئًا قَالَ انْظُرُوا هَلْ لِعَبْدِي مِنْ تَطَوُّعٍ فَإِنْ كَانَ لَهُ تَطَوُّعٌ قَالَ أَتِمُّوا لِعَبْدِي فَرِيضَتَهُ مِنْ تَطَوُّعِهِ ثُمَّ تُؤْخَذُ الأَعْمَالُ عَلَى ذَاكُمْ ‏"‏ ‏.‏

Narrated AbuHurayrah: Anas ibn Hakim ad-Dabbi said that he feared Ziyad or Ibn Ziyad; so he came to Medina and met AbuHurayrah. He attributed his lineage to me and I became a member of his lineage. AbuHurayrah said (to me): O youth, should I not narrate a tradition to you? I said: Why not, may Allah have mercy on you? (Yunus (a narrator) said: I think he narrated it (the tradition) from the Prophet (ﷺ):) The first thing about which the people will be called to account out of their actions on the Day of Judgment is prayer. Our Lord, the Exalted, will say to the angels - though He knows better: Look into the prayer of My servant and see whether he has offered it perfectly or imperfectly. If it is perfect, that will be recorded perfect. If it is defective, He will say: See there are some optional prayers offered by My servant. If there are optional prayer to his credit, He will say: Compensate the obligatory prayer by the optional prayer for My servant. Then all the actions will be considered similarly
