Tirmidhi Book 8, Hadith 731

حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا أَبُو الْأَحْوَصِ، عَنْ سِمَاكِ بْنِ حَرْبٍ، عَنْ ابْنِ أُمِّ هَانِئٍ، عَنْ أُمِّ هَانِئٍ، قَالَتْ:‏‏‏‏ كُنْتُ قَاعِدَةً عِنْدَ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَأُتِيَ بِشَرَابٍ فَشَرِبَ مِنْهُ، ‏‏‏‏‏‏ثُمَّ نَاوَلَنِي فَشَرِبْتُ مِنْهُ، ‏‏‏‏‏‏فَقُلْتُ:‏‏‏‏ إِنِّي أَذْنَبْتُ فَاسْتَغْفِرْ لِي، ‏‏‏‏‏‏فَقَالَ:‏‏‏‏ وَمَا ذَاكِ ؟ قَالَتْ:‏‏‏‏ كُنْتُ صَائِمَةً فَأَفْطَرْتُ، ‏‏‏‏‏‏فَقَالَ:‏‏‏‏ أَمِنْ قَضَاءٍ كُنْتِ تَقْضِينَهُ ، ‏‏‏‏‏‏قَالَتْ:‏‏‏‏ لَا، ‏‏‏‏‏‏قَالَ:‏‏‏‏ فَلَا يَضُرُّكِ . قَالَ:‏‏‏‏ وَفِي الْبَاب عَنْ أَبِي سَعِيدٍ، ‏‏‏‏‏‏وَعَائِشَةَ.

Umm Hani narrated: I was sitting with the Prophet when some drink was brought, so he drank from it, then he offered it to me and I drank it. Then I said: 'I have indeed sinned, so seek forgiveness for me.' He said: 'What is that?' I said: 'I was fasting, then I broke the fast.' He said: 'Were you performing a fast that you had to make up?' I said: 'No.' He said: 'Then it is no harm for you.'
