Arabic (Original)
حَدَّثَنَا مُحَمَّدُ بْنُ بِشْرٍ حَدَّثَنَا أَبُو حَيَّانَ عَنْ أَبِي زُرْعَةَ عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ نَبِيُّ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لِبِلَالٍ عِنْدَ صَلَاةِ الْفَجْرِ يَا بِلَالُ خَبِّرْنِي بِأَرْجَى عَمَلٍ عَمِلْتَهُ مَنْفَعَةً فِي الْإِسْلَامِ فَإِنِّي قَدْ سَمِعْتُ اللَّيْلَةَ خَشْفَ نَعْلَيْكَ بَيْنَ يَدَيَّ فِي الْجَنَّةِ قَالَ مَا عَمِلْتُ يَا رَسُولَ اللَّهِ فِي الْإِسْلَامِ عَمَلًا أَرْجَى عِنْدِي مَنْفَعَةً مِنْ أَنِّي لَمْ أَتَطَهَّرْ طُهُورًا تَامًّا قَطُّ فِي سَاعَةٍ مِنْ لَيْلٍ أَوْ نَهَارٍ إِلَّا صَلَّيْتُ بِذَلِكَ الطُّهُورِ لِرَبِّي مَا كُتِبَ لِي أَنْ أُصَلِّيَ.
English Translation
The Prophet of Allah (peace be upon him) said to Bilal at the time of the Fajr prayer: "O Bilal, tell me of the deed you have done in Islam that you hope will benefit you the most, for I heard the sound of your sandals ahead of me in Paradise last night." He said: "O Messenger of Allah, the most hopeful deed I have done in Islam is that I never performed a complete ablution at any hour of the night or day except that I prayed with that ablution whatever Allah had decreed for me to pray."
