عَنْ أُمِّ هَانِئٍ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: لَمَّا كَانَ يَوْمُ الْفَتْحِ فَتْحِ مَكَّةَ جَاءَتْ فَاطِمَةُ فَجَلَسَتْ عَلَى يَسَارِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَأَمُّ هَانِئٍ عَنْ يَمِينِهِ فَجَاءَتِ الْوَلِيدَةُ بِإِنَاءٍ فِيهِ شَرَابٌ فَنَاوَلَتْهُ فَشَرِبَ مِنْهُ ثُمَّ نَاوَلَهُ أُمَّ هَانِئٍ فَشَرِبَتْ مِنْهُ فَقَالَتْ: يَا رَسُولَ اللَّهِ لَقَدْ أَفْطَرْتُ وَكُنْتُ صَائِمَةً فَقَالَ لَهَا: «أَكُنْتِ تَقْضِينَ شَيْئًا؟» قَالَتْ: لَا. قَالَ: «فَلَا يَضُرُّكِ إِنْ كَانَ تَطَوُّعًا» . رَوَاهُ أَبُو دَاوُدَ وَالتِّرْمِذِيُّ وَالدَّارِمِيُّ وَفِي رِوَايَةٍ لِأَحْمَدَ وَالتِّرْمِذِيِّ نَحْوُهُ وَفِيهِ فَقَالَتْ: يَا رَسُولَ اللَّهِ أَمَا إِنِّي كُنْتُ صَائِمَةً فَقَالَ: «الصَّائِم أَمِيرُ نَفْسِهِ إِنْ شَاءَ صَامَ وَإِنْ شَاءَ أفطر»

Umm Hani’ said that on the day of the conquest of Mecca Fatima came and sat on God’s messenger’s left and Umm Hani on his right, and when the maidservant brought a vessel containing; drinking water and handed it to him, he drank some of it and handed it to Umm Hani’ who drank some of it. She then said, “Messenger of God, I was fasting and I have broken my fast.” He asked if she was making up for anything, and when she replied that she was not, he said, “It will not harm you if it was a voluntary fast.” Abu Dawud, Tirmidhi and Darimi transmitted it. A version by Ahmad and Tirmidhi has something similar. In it she said, “Messenger of God, I was fasting,” and he replied, “The one who observes a voluntary fast is his own master; if he wishes he may fast, and if he wishes he may break it.”
