We were with ʿUthman bin ʿAffan ؓ , he called for water and did wudoo’. When he had finished his wudooʿ, he smiled and said: Do you know why I smiled? He said: The Messenger of Allah ﷺ did wudooʿ as I just did wudooʿ, then he smiled and said: “Do you know why I smiled?ʿ we said: Allah and His Messenger know best. He said: “If a person does wudoo and completes his wudoo’, then he starts to pray and completes his prayer, he will come out of his prayer free of sin as he came out of his motherʿs womb.”  

تَوَضَّأَ رَسُولُ اللهِ ﷺ كَمَا تَوَضَّأْتُ ثُمَّ تَبَسَّمَ ثُمَّ قَالَ هَلْ تَدْرُونَ مِمَّ ضَحِكْتُ؟ قَالَ قُلْنَا اللهُ وَرَسُولُهُ أَعْلَمُ قَالَ إِنَّ الْعَبْدَ إِذَا تَوَضَّأَ فَأَتَمَّ وُضُوءَهُ ثُمَّ دَخَلَ فِي صَلاتِهِ فَأَتَمَّ صَلاتَهُ خَرَجَ مِنْ صَلاتِهِ كَمَا خَرَجَ مِنْ بَطْنِ أُمِّهِ مِنَ الذُّنُوبِ  

" عَنْ حُمْرَانَ قَالَ: كُنْتُ عِنْدَ عثمَانَ فَدَعَا بِوَضُوء فَتَوضَّأ، فَلَمَّا فَرَغَ قَالَ: تَوَضَّأ رَسُولُ الله ﷺ كَمَا تَوَضَّأتُ، ثُمَّ تَبَسَّمَ، فَقَالَ: أَتَدْرُونَ مِمَّ ضَحِكْتُ؟ قُلْنَا: الله وَرَسُولُهُ أعْلَمُ، قَالَ: إِنَّ الْعَبْدَ الْمُسْلِمَ إِذَا تَوَضَّأ فَأتَمَّ وضُوءَهُ، ثُمَّ دَخَلَ فىِ صَلاَتِهِ فَأتَّمَ صَلاَتَهُ، خَرَجَ مِنَ (الذُّنُوبِ) كمَا خَرجَ مِنْ بَطنِ أُمِّهِ ".
