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. (Using translation from Abū Dāʾūd 905)

قَالَ رَسُولُ اللهِ ﷺ «مَنْ تَوَضَّأَ فَأَحْسَنَ الْوُضُوءَ ثُمَّ صَلَّى رَكْعَتَيْنِ لَا يَسْهُوَ فِيهِمَا غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ»
