Narrated 'Aishah, wife of Prophet ﷺ:
A man said to Messenger of Allah ﷺ: Messenger of Allah, I was overtaken by dawn while I was sexually defiled, and I want to keep fast. The Messenger of Allah ﷺ said: I am also overtaken by dawn while I am in the state of sexual defilement ; I also want to keep fast. I take a bath and I keep fast. The man said: Messenger of Allah, you are not like us ; Allah has forgiven you your past and future sins. The Messenger of Allah ﷺ became angry and said: I swear by Allah, I hope I shall be the most fearful of you of Allah, and most familiar of you with what I follow.

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، - يَعْنِي الْقَعْنَبِيَّ - عَنْ مَالِكٍ، عَنْ عَبْدِ اللَّهِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ مَعْمَرٍ الأَنْصَارِيِّ، عَنْ أَبِي يُونُسَ، مَوْلَى عَائِشَةَ عَنْ عَائِشَةَ، زَوْجِ النَّبِيِّ ﷺ أَنَّ رَجُلاً قَالَ لِرَسُولِ اللَّهِ ﷺ وَهُوَ وَاقِفٌ عَلَى الْبَابِ يَا رَسُولَ اللَّهِ إِنِّي أُصْبِحُ جُنُبًا وَأَنَا أُرِيدُ الصِّيَامَ . فَقَالَ رَسُولُ اللَّهِ ﷺ " وَأَنَا أُصْبِحُ جُنُبًا وَأَنَا أُرِيدُ الصِّيَامَ فَأَغْتَسِلُ وَأَصُومُ " . فَقَالَ الرَّجُلُ يَا رَسُولَ اللَّهِ إِنَّكَ لَسْتَ مِثْلَنَا قَدْ غَفَرَ اللَّهُ لَكَ مَا تَقَدَّمَ مِنْ ذَنْبِكَ وَمَا تَأَخَّرَ فَغَضِبَ رَسُولُ اللَّهِ ﷺ وَقَالَ " وَاللَّهِ إِنِّي لأَرْجُو أَنْ أَكُونَ أَخْشَاكُمْ لِلَّهِ وَأَعْلَمَكُمْ بِمَا أَتَّبِعُ " .
