Mishkat al-Masabih 3 Purification كتاب الطهارة 7

وَعَنْ عُقْبَةَ بْنِ عَامِرٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَا مِنْ مُسْلِمٍ يَتَوَضَّأُ فَيُحْسِنُ وُضُوءَهُ ثُمَّ يَقُومُ فَيُصَلِّي رَكْعَتَيْنِ مقبل عَلَيْهِمَا بِقَلْبِهِ وَوَجْهِهِ إِلَّا وَجَبَتْ لَهُ الْجَنَّةُ» . رَوَاهُ مُسلم

‘Uqba b. ‘Amir reported God’s messenger as saying, “If any Muslim performs ablution well, then stands and prays two rak’as , setting about their performance both inwardly and outwardly, he will be guaranteed paradise.” Muslim transmitted it.
