I came to ‘Uthman bin ʿAffan ؓ when he was sitting in al-Maqaʿid. He did wudoo and did it well, then he said: I saw the Messenger of Allah ﷺ when he was in this place; he did wudoo’ and did it well, then he said: “Whoever does wudoo’ as I have done, then goes to the mosque and prays two rakats, his previous sins will be forgiven.” And he said: The Messenger of Allah ﷺ said: ʿDo not become complacent.”
رَأَيْتُ رَسُولَ اللهِ ﷺ وَهُوَ فِي هَذَا الْمَجْلِسِ تَوَضَّأَ فَأَحْسَنَ الْوُضُوءَ ثُمَّ قَالَ وَقَالَ مَنْ تَوَضَّأَ مِثْلَ وُضُوئِي هَذَا ثُمَّ أَتَى الْمَسْجِدَ فَرَكَعَ فِيهِ رَكْعَتَيْنِ غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ وَقَالَ قَالَ رَسُولُ اللهِ ﷺ وَلا تَغْتَرُّوا
