سنن أبي داود#905Hasanحَدَّثَنَا أَحْمَدُ بْنُ مُحَمَّدِ بْنِ حَنْبَلٍ، حَدَّثَنَا عَبْدُ الْمَلِكِ بْنُ عَمْرٍو، حَدَّثَنَا هِشَامٌ، - يَعْنِي ابْنَ سَعْدٍ - عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ عَطَاءِ بْنِ يَسَارٍ، عَنْ زَيْدِ بْنِ خَالِدٍ الْجُهَنِيِّ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ " مَنْ تَوَضَّأَ فَأَحْسَنَ وُضُوءَهُ ثُمَّ صَلَّى رَكْعَتَيْنِ لاَ يَسْهُو فِيهِمَا غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ " .
Zaid b. Khalid al-Juhani reported the Messenger of Allah (ﷺ) as saying:Anyone who performs ablution and performs his ablution well, and then he offers two rak’ahs of prayers in a way that he does not forget ( anything in it), will be forgiven all his past sins
