I heard the Messenger of Allah ﷺ say: “Whoever does wudooʿ and does it properly, then goes and offers an obligatory prayer, his sins will be forgiven.ʿ
أَنَّهُ قَالَ سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ مَنْ تَوَضَّأَ فَأَسْبَغَ الْوُضُوءَ ثُمَّ مَشَى إِلَى صَلاةٍ مَكْتُوبَةٍ فَصَلَّاهَا غُفِرَ لَهُ ذَنْبُهُ
