One day Uthman b. Affan performed the ablution well, and then said: I saw Messenger of Allah ﷺ perform ablution, the best ablution, and then observed: He who performed ablution like this and then went towards the mosque and nothing (but the love of) prayer urged him (to do so), all his previous (minor) sins would be expiated.  

رَأَيْتُ رَسُولَ اللَّهِ ﷺ تَوَضَّأَ فَأَحْسَنَ الْوُضُوءَ ثُمَّ قَالَ مَنْ تَوَضَّأَ هَكَذَا ثُمَّ خَرَجَ إِلَى الْمَسْجِدِ لاَ يَنْهَزُهُ إِلاَّ الصَّلاَةُ غُفِرَ لَهُ مَا خَلاَ مِنْ ذَنْبِهِ  

"عَنْ عُثْمانَ قَالَ: رَأَيْت رَسُولَ الله ﷺ تَوَضَّأ فَأحْسَنَ الوُضُوءَ، ثُمَّ قَال: مَنْ تَوَضأ وضُوئى هَذا، ثُمَّ أَتَى المَسْجِد فَرَكَع رَكْعَتَين غُفِرَ لَه مَا تَقَدَّمَ مِن ذَنْبه".
