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.  

عَنِ النَّبِيِّ ﷺ 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

(Using translation from Abū Dāʾūd 864)   

يَا فَتَى أَلَا أُحَدِّثُكَ حَدِيثًا لَعَلَّ اللهَ أَنْ يَنْفَعَكَ بِهِ؟ قُلْتُ بَلَى يَرْحَمُكَ اللهُ قَالَ إِنَّ مِنْ أَوَّلَ مَا يُحَاسَبُ بِهِ النَّاسُ يَوْمَ الْقِيَامَةِ الصَّلَاةُ قَالَ يَقُولُ رَبُّنَا ﷻ لِمَلَائِكَتِهِ وَهُوَ أَعْلَمُ انْظُرُوا فِي صَلَاةِ 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 تَطَوُّعِهِثُمَّ تُؤْخَذُ الْأَعْمَالُ عَلَى ذَاكُمْ قَالَ يُونُسُ وَأَحْسَبُهُ قَدْ ذَكَرَ النَّبِيَّ ﷺ  

[Machine] On the authority of the Messenger of Allah ﷺ , he said, "Verily, the first thing for which people will be held to account on the Day of Resurrection from their actions is their prayer. Our Lord, the Exalted, will say to His angels while He knows better, 'Look at the prayer of My servant; did he complete it or fall short?' If it is complete, it will be recorded as complete for him, but if it is deficient, He will say, 'Look for voluntary prayers for My servant. If he has any, complete his obligatory prayer with it.' Then, the rest of his deeds will be dealt with accordingly." And Abu Ali ar-Rudhbary narrated on the authority of Abu Bakr bin Dasa, who narrated from Abu Dawud, who narrated from Musa bin Ismail, who narrated from Hammad, who narrated from Humaid, who narrated from a man from Banu Salit, who narrated from Abu Hurayrah, who narrated from the Prophet ﷺ similar to this hadith. Hassan differed in many aspects of this hadith, and we have mentioned the most correct of them, if Allah wills. And it was narrated from Yahya bin Ya'mur, from Abu Hurayrah, that it is Marfu' (elevated).  

عَنْ رَسُولِ اللهِ ﷺ قَالَ إِنَّ أَوَّلَ مَا يُحَاسَبُ النَّاسُ بِهِ يَوْمَ الْقِيَامَةِ مِنْ أَعْمَالِهِمُ الصَّلَاةُ قَالَ يَقُولُ رَبُّنَا ﷻ لِمَلَائِكَتِهِ وَهُوَ أَعْلَمُ انْظُرُوا فِي صَلَاةِ عَبْدِي أَتَمَّهَا أَمْ نَقَصَهَا؟ فَإِنْ كَانَتْ تَامَّةً كُتِبَتْ لَهُ تَامَّةً وَإِنْ كَانَتِ انْتَقَصَ مِنْهَا شَيْئًا قَالَ انْظُرُوا هَلْ لِعَبْدِي مِنْ تَطَوُّعٍ فَإِنْ كَانَ لَهُ تَطَوُّعٌ قَالَ أَتِمُّوا لِعَبْدِي فَرِيضَتَهُ مِنْ تَطَوُّعِهِ ثُمَّ تُأْخَذُ الْأَعْمَالُ عَلَى ذَلِكُمْ 4001 وَأنبأ أَبُو عَلِيٍّ الرُّوذْبَارِيُّ أنبأ أَبُو بَكْرِ بْنُ دَاسَةَ ثنا أَبُو دَاوُدَ ثنا مُوسَى بْنُ إِسْمَاعِيلَ ثنا حَمَّادٌ عَنْ حُمَيْدٍ عَنِ الْحَسَنِ عَنْ رَجُلٍ مِنْ بَنِي سَلِيطٍ عَنْ أَبِي هُرَيْرَةَ ؓ عَنِ النَّبِيِّ ﷺ نَحْوَهُ هَذَا حَدِيثٌ قَدِ اخْتَلَفَ فِيهِ الْحَسَنُ مِنْ أَوْجُهٍ كَثِيرَةٍ وَمَا ذَكَرْنَا أَصَحَّهَا إِنْ شَاءَ اللهُ تَعَالَى وَرُوِيَ عَنْ يَحْيَى بْنِ يَعْمُرَ عَنْ أَبِي هُرَيْرَةَ ؓ مَرْفُوعًا  

"أَوَّلُ ما يحاسبُ النَّاسُ بهِ يَوْم القيامَةِ من أَعمالهم الصَّلاةُ، يقولُ ربُّنَا ﷻ لملائكتِهِ وهو أَعْلَمُ: انْظُرُوا في صَلَاة عَبْدِى أتَمَهَا أَمْ نَقَصهَا؟ فإنْ كَانت تَامَّةً كُتبتْ لَهُ تَامَّةً، وإِن كَانَ انتَقَصَ مِنْهَا شيْئًا، قال: انْظُرُوا: هل لعبدى من تَطَوَّع؟ فإِن كان له تَطُوُّعٌ، قال: أَتِمُّوا لعبدى فريضتَهُ من تَطوُّعِهِ، ثُمَّ تُؤْخذُ الأعمالُ على ذَاكُمْ ".
