Sahih Bukhari Volume 3, Book 30, Hadith 1936

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُنِيرٍ، سَمِعَ يَزِيدَ بْنَ هَارُونَ، حَدَّثَنَا يَحْيَى ـ هُوَ ابْنُ سَعِيدٍ ـ أَنَّ عَبْدَ الرَّحْمَنِ بْنَ الْقَاسِمِ، أَخْبَرَهُ عَنْ مُحَمَّدِ بْنِ جَعْفَرِ بْنِ الزُّبَيْرِ بْنِ الْعَوَّامِ بْنِ خُوَيْلِدٍ، عَنْ عَبَّادِ بْنِ عَبْدِ اللَّهِ بْنِ الزُّبَيْرِ، أَخْبَرَهُ أَنَّهُ، سَمِعَ عَائِشَةَ ـ رضى الله عنها ـ تَقُولُ إِنَّ رَجُلاً أَتَى النَّبِيَّ صلى الله عليه وسلم فَقَالَ إِنَّهُ احْتَرَقَ‏.‏ قَالَ ‏"‏ مَالَكَ ‏"‏‏.‏ قَالَ أَصَبْتُ أَهْلِي فِي رَمَضَانَ‏.‏ فَأُتِيَ النَّبِيُّ صلى الله عليه وسلم بِمِكْتَلٍ، يُدْعَى الْعَرَقَ فَقَالَ ‏"‏ أَيْنَ الْمُحْتَرِقُ ‏"‏‏.‏ قَالَ أَنَا‏.‏ قَالَ ‏"‏ تَصَدَّقْ بِهَذَا ‏"

Narrated By 'Aisha : A man came to the Prophet and said that he had been burnt (ruined). The Prophet asked him what was the matter. He replied, "I had sexual intercourse with my wife in Ramadan (while I was fasting)." Then a basket full of dates was brought to the Prophet and he asked, "Where is the burnt (ruined) man?" He replied, "I am present." The Prophet told him to give that basket in charity (as expiation).
