He who performed ablution for prayer and performed it properly and then went (to observe) obligatory prayer and offered it along with people or with the congregation or in the mosque, Allah would pardon his sins.  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَنْ تَوَضَّأَ لِلصَّلاَةِ فَأَسْبَغَ الْوُضُوءَ ثُمَّ مَشَى إِلَى الصَّلاَةِ الْمَكْتُوبَةِ فَصَلاَّهَا مَعَ النَّاسِ أَوْ مَعَ الْجَمَاعَةِ أَوْ فِي الْمَسْجِدِ غَفَرَ اللَّهُ لَهُ ذُنُوبَهُ  

"I heard the Messenger of Allah ﷺ say: 'Whoever does wudu' properly, then walks to (attend) the prescribed prayer, and prays with the people or with the congregation or in the Masjid, Allah will forgive him his sins."  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَنْ تَوَضَّأَ لِلصَّلاَةِ فَأَسْبَغَ الْوُضُوءَ ثُمَّ مَشَى إِلَى الصَّلاَةِ الْمَكْتُوبَةِ فَصَلاَّهَا مَعَ النَّاسِ أَوْ مَعَ الْجَمَاعَةِ أَوْ فِي الْمَسْجِدِ غَفَرَ اللَّهُ لَهُ ذُنُوبَهُ  

I heard the Messenger of Allah ﷺ say: “Whoever does wudooʿ and does it properly, then goes and offers an obligatory prayer, his sins will be forgiven.ʿ  

أَنَّهُ قَالَ سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ مَنْ تَوَضَّأَ فَأَسْبَغَ الْوُضُوءَ ثُمَّ مَشَى إِلَى صَلاةٍ مَكْتُوبَةٍ فَصَلَّاهَا غُفِرَ لَهُ ذَنْبُهُ  

He who performed ablution for prayer and performed it properly and then went (to observe) obligatory prayer and offered it along with people or with the congregation or in the mosque, Allah would pardon his sins. (Using translation from Muslim 232b)  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «مَنْ تَوَضَّأَ لِلصَّلَاةِ فَأَسْبَغَ الْوُضُوءَ ثُمَّ مَشَى إِلَى الصَّلَاةِ الْمَكْتُوبَةِ فَصَلَّاهَا مَعَ النَّاسِ أَوْ مَعَ الْجَمَاعَةِ أَوْ فِي الْمَسْجِدِ غُفِرَ لَهُ ذَنْبُهُ»  

"مَنْ تَوَضَّأَ لِلصَّلاةِ فأَسْبَغَ الْوُضُوءَ، ثُمَّ مَشَى إِلَى الصَّلاةِ الْمكْتُوبة فَصَلَّاهَا مَعَ النَّاس غُفِرَ لَهُ ذُنُوبُه".
