"I arrived in Al-Madinah and said: 'O Allah, make it easy for me to find a righteous companion.' Then I sat with Abu Hurairah, may Allah be pleased with him, and said: 'I prayed to Allah to help me find a righteous companion.' So tell me a Hadith that you heard from the Messenger of Allah ﷺ, so that Allah might benefit me from it. He said: 'I heard the Messenger of Allah ﷺ say: "The first thing for which a person will be brought to account will be his Salah. If it is sound then he will have succeeded, be salvaged, but if it is not then he will have lost and be doomed." - (One of the narrators) Hammam said: "I do not know whether this was the words of Qatadah or part of the report." - "If anything is lacking from his obligatory prayers, He will say: 'Look and see whether My slave has any voluntary prayers to make up for what is deficient from his obligatory prayers.' Then all of his deeds will be dealt with in like manner."  

قُلْتُ اللَّهُمَّ يَسِّرْ لِي جَلِيسًا صَالِحًا فَجَلَسْتُ إِلَى أَبِي هُرَيْرَةَ ؓ قَالَ فَقُلْتُ إِنِّي دَعَوْتُ اللَّهَ ﷻ أَنْ يُيَسِّرَ لِي جَلِيسًا صَالِحًا فَحَدِّثْنِي بِحَدِيثٍ سَمِعْتَهُ مِنْ رَسُولِ اللَّهِ ﷺ لَعَلَّ اللَّهَ أَنْ يَنْفَعَنِي بِهِ قَالَ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِنَّ أَوَّلَ مَا يُحَاسَبُ بِهِ الْعَبْدُ بِصَلاَتِهِ فَإِنْ صَلَحَتْ فَقَدْ أَفْلَحَ وَأَنْجَحَ وَإِنْ فَسَدَتْ فَقَدْ خَابَ وَخَسِرَ قَالَ هَمَّامٌ لاَ أَدْرِي هَذَا مِنْ كَلاَمِ قَتَادَةَ أَوْ مِنَ الرِّوَايَةِ فَإِنِ انْتَقَصَ مِنْ فَرِيضَتِهِ شَىْءٌ قَالَ انْظُرُوا هَلْ لِعَبْدِي مِنْ تَطَوُّعٍ فَيُكَمَّلُ بِهِ مَا نَقَصَ مِنَ الْفَرِيضَةِ ثُمَّ يَكُونُ سَائِرُ عَمَلِهِ عَلَى نَحْوِ ذَلِكَ خَالَفَهُ أَبُو الْعَوَّامِ  

"I arrived in Al-Madinah and said: 'O Allah! Facilitate me to be in a righteous gathering.'" He said: "I sat with Abu Hurairah and said: 'Indeed I asked Allah to provide me with a righteous gathering. So narrate a hadith to me which you heard from Messenger of Allah ﷺ so that perhaps Allah would cause me to benefit from it.' He said: 'I heard Messenger of Allah ﷺ say: "Indeed the first deed by which a servant will be called to account on the Day of Resurrection is his Salat. If it is complete, he is successful and saved, but if it is defective, he has failed and lost. So if something is deficient in his obligatory (prayers) then the Lord, Mighty and Sublime says: 'Look! Are there any voluntary (prayers) for my worshipper?' So with them, what was deficient in his obligatory (prayers) will be completed. Then the rest of his deeds will be treated like that."  

قَدِمْتُ الْمَدِينَةَ فَقُلْتُ اللَّهُمَّ يَسِّرْ لِي جَلِيسًا صَالِحًا قَالَ فَجَلَسْتُ إِلَى أَبِي هُرَيْرَةَ فَقُلْتُ إِنِّي سَأَلْتُ اللَّهَ أَنْ يَرْزُقَنِي جَلِيسًا صَالِحًا فَحَدِّثْنِي بِحَدِيثٍ سَمِعْتَهُ مِنْ رَسُولِ اللَّهِ ﷺ لَعَلَّ اللَّهَ أَنْ يَنْفَعَنِي بِهِ فَقَالَ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِنَّ أَوَّلَ مَا يُحَاسَبُ بِهِ الْعَبْدُ يَوْمَ الْقِيَامَةِ مِنْ عَمَلِهِ صَلاَتُهُ فَإِنْ صَلُحَتْ فَقَدْ أَفْلَحَ وَأَنْجَحَ وَإِنْ فَسَدَتْ فَقَدْ خَابَ وَخَسِرَ فَإِنِ انْتَقَصَ مِنْ فَرِيضَتِهِ شَيْءٌ قَالَ الرَّبُّ ﷻ انْظُرُوا هَلْ لِعَبْدِي مِنْ تَطَوُّعٍ فَيُكَمَّلَ بِهَا مَا انْتَقَصَ مِنَ الْفَرِيضَةِ ثُمَّ يَكُونُ سَائِرُ عَمَلِهِ عَلَى ذَلِكَ قَالَ وَفِي الْبَابِ عَنْ تَمِيمٍ الدَّارِيِّ  

"إِنَّ أَوَّلَ مَا يُحَاسَبُ به الْعبْدُ يَوم الْقِيامةِ مِن عملِهِ صَلَاتُهُ، فَإِنْ صَلَحَتْ فَقَدْ أفْلَحَ وَنَجَحَ، وَإنْ فَسَدَتْ فَقَدْ خَابَ وَخَسِرَ، وَإنْ انْتَقَصَ مِنْ فَرِيضَتِهِ قَالَ الرَّبُّ: انْظُرُوا هَلْ لِعَبْدِى مِنْ تَطَوُّعُ فَيُكْمِل بِهَا مَا انْتَقَصَ منَ الفَريضَة، ثُمَّ يَكُونُ سَائِرُ عمَلِهِ عَلَى ذَلكَ".
