‘Abbad al-‘Abdi reported: The Messenger of Allah, peace and blessings be upon him, said, “No servant performs ablution in an excellent manner such that water covers his face, then he washes his arms until water covers his elbows, then he washes his feet until water covers his heels, and then he prays in an excellent manner, but that he will be forgiven for what he had done before.”

عَنْ عباد العبدي عَنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَا مِنْ عَبْدٍ يَتَوَضَّأُ فَيُحْسِنُ وُضُوءَهُ حَتَّى يَسِيلَ الْمَاءُ عَلَى وَجْهِهِ ثُمَّ يَغْسِلُ ذِرَاعَيْهِ حَتَّى يَسِيلَ الْمَاءُ عَلَى مِرْفَقَيْهِ ثُمَّ يَغْسِلُ قَدَمَيْهِ حَتَّى يَسِيلَ الْمَاءُ مِنْ قِبَلِ عَقِبَيْهِ ثُمَّ يُصَلِّي فَيُحْسِنُ صَلاتَهُ إِلا غُفِرَ لَهُ مَا سَلَفَ
