عَنْ أُمِّ هَانِئٍ (بِنْتِ أَبِي طَالِبٍ) رَضِيَ اللَّهُ عَنْهَا أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ شَرِبَ شَرَابًا فَنَاوَلَهَا لِتَشْرَبَ، فَقَالَتْ: إِنِّي صَائِمَةٌ وَلَكِنِّي كَرِهْتُ أَنْ أَرُدَّ سُؤْرَكَ، فَقَالَ: ((إِنْ كَانَ قَضَاءً مِنْ رَمَضَانَ فَاقْضِي يَوْمًا مَكَانَهُ، وَإِنْ كَانَ تَطَوُّعًا فَإِنْ شِئْتِ فَاقْضِي وَإِنْ شِئْتِ فَلَا تَقْضِي))
Narrated by Sayyida Umm Hani bint Abi Talib (may Allah be pleased with her), she says: The Messenger of Allah (peace and blessings be upon him) drank a beverage and gave it to me as well. Later, I said: I was fasting, but I could not bear to leave what was left by you. The Prophet (peace and blessings be upon him) said: If this fast was a make-up for Ramadan, then keep one fast in its place, and if it was a voluntary fast, then it is up to you whether you make it up or not.
