قَالَ حَدَّثَنَا عَفَّانُ حَدَّثَنَا أَبُو عَوَانَةَ عَنْ إِبْرَاهِيمَ بْنِ الْمُهَاجِرِ عَنْ عِكْرِمَةَ بْنِ خَالِدٍ حَدَّثَنِي رَجُلٌ مِنْ أَهْلِ الْمَدِينَةِ أَنَّ الْمُؤَذِّنَ أَذَّنَ لِصَلَاةِ الْعَصْرِ قَالَ فَدَعَا عُثْمَانُ رَضِيَ اللَّهُ عَنْهُ بِطَهُورٍ فَتَطَهَّرَ قَالَ ثُمَّ قَالَ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ مَنْ تَطَهَّرَ كَمَا أُمِرَ وَصَلَّى كَمَا أُمِرَ كُفِّرَتْ عَنْهُ ذُنُوبُهُ فَاسْتَشْهَدَ عَلَى ذَلِكَ أَرْبَعَةً مِنْ أَصْحَابِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ فَشَهِدُوا لَهُ بِذَلِكَ عَلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ
مسند امام احمد بن حنبل · Hadith 486
It was narrated from 'Ikrimah bin Khalid: a man from Madinah told me that the ntu’adhdhin gave the call to Asr prayer and ' Uthman (RA) called for water and purified himself, then he said: I heard the Messenger of Allah (PBUH) say: "Whoever purifies himself as he has been enjoined and prays as he has been enjoined, his sins will be expiated." Then he called four of the Companions of the Messenger of Allah (PBUH) to testify to that, and they testified that the Prophet (PBUH) had said that.
