Sunan an-Nasa'i 849
It was narrated that 'Abdullah said:
"Whoever would like to meet Allah tomorrow as a Muslim, let  him regularly attend these five (daily) prayers  whenever the call for them is given (that in the mosques), for Allah prescribed for
His Prophet the ways of guidance, and they (the prayers) are part of those ways of guidance. I do not think that there is anyone among you who does not have a place where he prays in his house. But if you were to pray in your houses and forsake the Masjids, you would be forsaking the Sunnah of your Prophet, and if you were to forsake the Sunnah of your
Prophet you would go astray. There is no Muslim slave who performs Wudu and does it well, then walks to the prayer, but Allah will record one Hasanah (good
deed) for each step he takes, or raise' him one level by it or erase one sin from him. I remember how we used to take short steps, and I remember (a time) when no one stayed behind from the prayer except
a hypocrite whose hypocrisy was well known. And I have seen a man coming Supported by two others until he would be made to stand in the row."
أَخْبَرَنَا سُوَيْدُ بْنُ نَصْرٍ، قَالَ أَنْبَأَنَا عَبْدُ اللَّهِ بْنُ الْمُبَارَكِ، عَنِ الْمَسْعُودِيِّ، عَنْ عَلِيِّ بْنِ الأَقْمَرِ، عَنْ أَبِي الأَحْوَصِ، عَنْ عَبْدِ اللَّهِ، أَنَّهُ كَانَ يَقُولُ مَنْ سَرَّهُ أَنْ يَلْقَى اللَّهَ عَزَّ وَجَلَّ غَدًا مُسْلِمًا فَلْيُحَافِظْ عَلَى هَؤُلاَءِ الصَّلَوَاتِ الْخَمْسِ حَيْثُ يُنَادَى بِهِنَّ فَإِنَّ اللَّهَ عَزَّ وَجَلَّ شَرَعَ لِنَبِيِّهِ صلى الله عليه وسلم سُنَنَ الْهُدَى وَإِنَّهُنَّ مِنْ سُنَنِ الْهُدَى وَإِنِّي لاَ أَحْسَبُ مِنْكُمْ أَحَدًا إِلاَّ لَهُ مَسْجِدٌ يُصَلِّي فِيهِ فِي بَيْتِهِ فَلَوْ صَلَّيْتُمْ فِي بُيُوتِكُمْ وَتَرَكْتُمْ مَسَاجِدَكُمْ لَتَرَكْتُمْ سُنَّةَ نَبِيِّكُمْ وَلَوْ تَرَكْتُمْ سُنَّةَ نَبِيِّكُمْ لَضَلَلْتُمْ وَمَا مِنْ عَبْدٍ مُسْلِمٍ يَتَوَضَّأُ فَيُحْسِنُ الْوُضُوءَ ثُمَّ يَمْشِي إِلَى صَلاَةٍ إِلاَّ كَتَبَ اللَّهُ عَزَّ وَجَلَّ لَهُ بِكُلِّ خُطْوَةٍ يَخْطُوهَا حَسَنَةً أَوْ يَرْفَعُ لَهُ بِهَا دَرَجَةً أَوْ يُكَفِّرُ عَنْهُ بِهَا خَطِيئَةً وَلَقَدْ رَأَيْتُنَا نُقَارِبُ بَيْنَ الْخُطَا وَلَقَدْ رَأَيْتُنَا وَمَا يَتَخَلَّفُ عَنْهَا إِلاَّ مُنَافِقٌ مَعْلُومٌ نِفَاقُهُ وَلَقَدْ رَأَيْتُ الرَّجُلَ يُهَادَى بَيْنَ الرَّجُلَيْنِ حَتَّى يُقَامَ فِي الصَّفِّ ‏.‏
