Mishkat al-Masabih, 1145

Abu Huraira reported God s Messenger as saying, “If anyone performs ablution, doing it well, then goes and finds that the people have finished the prayer, God will give him a reward equivalent to that of those who prayed and were present at it without that diminishing anything from their rewards.” Abu Dawud and Nasa’i transmitted it.

وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ تَوَضَّأَ فَأَحْسَنَ وُضُوءَهُ ثُمَّ رَاحَ فَوَجَدَ النَّاسَ قَدْ صَلَّوْا أَعْطَاهُ اللَّهُ مِثْلَ أَجْرِ مَنْ صَلَّاهَا وَحَضَرَهَا لَا يَنْقُصُ ذَلِكَ م أُجُورهم شَيْئا» . رَوَاهُ أَبُو دَاوُد وَالنَّسَائِيّ
