A man kissed a woman (unlawfully) and then went to the Prophet ﷺ and informed him. Allah revealed: And offer prayers perfectly At the two ends of the day And in some hours of the night (i.e. the five compulsory prayers). Verily! good deeds remove (annul) the evil deeds (small sins) (11.114). The man asked Messenger of Allah ﷺ, "Is it for me?" He said, "It is for all my followers."  

أَنَّ رَجُلاً أَصَابَ مِنَ امْرَأَةٍ قُبْلَةً فَأَتَى النَّبِيَّ ﷺ فَأَخْبَرَهُ فَأَنْزَلَ اللَّهُ {أَقِمِ الصَّلاَةَ طَرَفَىِ النَّهَارِ وَزُلَفًا مِنَ اللَّيْلِ إِنَّ الْحَسَنَاتِ يُذْهِبْنَ السَّيِّئَاتِ} فَقَالَ الرَّجُلُ: يَا رَسُولَ اللَّهِ، أَلِي هَذَا قَالَ: «لِجَمِيعِ أُمَّتِي كُلِّهِمْ۔»  

While I was with the Prophet ﷺ a man came and said, "O Messenger of Allah ﷺ! I have committed a legally punishable sin; please inflict the legal punishment on me'.' The Prophet ﷺ did not ask him what he had done. Then the time for the prayer became due and the man offered prayer along with the Prophet ﷺ , and when the Prophet ﷺ had finished his prayer, the man again got up and said, "O Messenger of Allah ﷺ! I have committed a legally punishable sin; please inflict the punishment on me according to Allah's Laws." The Prophet ﷺ said, "Haven't you prayed with us?' He said, "Yes." The Prophet ﷺ said, "Allah has forgiven your sin." or said, "....your legally punishable sin."  

كُنْتُ عِنْدَ النَّبِيِّ ﷺ فَجَاءَهُ رَجُلٌ فَقَالَ يَا رَسُولَ اللَّهِ إِنِّي أَصَبْتُ حَدًّا فَأَقِمْهُ عَلَىَّ قَالَ وَلَمْ يَسْأَلْهُ عَنْهُ قَالَ وَحَضَرَتِ الصَّلاَةُ فَصَلَّى مَعَ النَّبِيِّ ﷺ فَلَمَّا قَضَى النَّبِيُّ ﷺ الصَّلاَةَ قَامَ إِلَيْهِ الرَّجُلُ فَقَالَ يَا رَسُولَ اللَّهِ إِنِّي أَصَبْتُ حَدًّا فَأَقِمْ فِيَّ كِتَابَ اللَّهِ قَالَ أَلَيْسَ قَدْ صَلَّيْتَ مَعَنَا قَالَ نَعَمْ قَالَ فَإِنَّ اللَّهَ قَدْ غَفَرَ لَكَ ذَنْبَكَ أَوْ قَالَ حَدَّكَ
