وحَدَّثَنَا أَبُو كَامِلٍ فُضَيْلُ بْنُ حُسَيْنٍ ، حَدَّثَنَا عَبْدُ الْوَاحِدِ بْنُ زِيَادٍ ، حَدَّثَنَا طَلْحَةُ بْنُ يَحْيَى بْنِ عُبَيْدِ اللَّهِ ، حَدَّثَتْنِي عَائِشَةُ بِنْتُ طَلْحَةَ ، عَنْ عَائِشَةَ أُمِّ الْمُؤْمِنِينَ رَضِيَ اللَّهُ عَنْهَا ، قَالَتْ : قَالَ لِي رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ذَاتَ يَوْمٍ : " يَا عَائِشَةُ ، هَلْ عِنْدَكُمْ شَيْءٌ ؟ " ، قَالَتْ : فَقُلْتُ : يَا رَسُولَ اللَّهِ ، مَا عِنْدَنَا شَيْءٌ ، قَالَ : " فَإِنِّي صَائِمٌ " ، قَالَتْ : فَخَرَجَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، فَأُهْدِيَتْ لَنَا هَدِيَّةٌ ، أَوْ جَاءَنَا زَوْرٌ ، قَالَتْ : فَلَمَّا رَجَعَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، قُلْتُ : يَا رَسُولَ اللَّهِ ، أُهْدِيَتْ لَنَا هَدِيَّةٌ أَوْ جَاءَنَا زَوْرٌ ، وَقَدْ خَبَأْتُ لَكَ شَيْئًا ، قَالَ : " مَا هُوَ ؟ " ، قُلْتُ : حَيْسٌ ، قَالَ : " هَاتِيهِ " ، فَجِئْتُ بِهِ ، " فَأَكَلَ " ، ثُمَّ قَالَ : " قَدْ كُنْتُ أَصْبَحْتُ صَائِمًا " ، قَالَ طَلْحَةُ فَحَدَّثْتُ مُجَاهِدًا بِهَذَا الْحَدِيثِ ، فَقَالَ : ذَاكَ بِمَنْزِلَةِ الرَّجُلِ يُخْرِجُ الصَّدَقَةَ مِنْ مَالِهِ فَإِنْ شَاءَ أَمْضَاهَا ، وَإِنْ شَاءَ أَمْسَكَهَا .
'A'isha, the Mother of the Believers (Allah be pleased with her), reported that one day the Messenger of Allah (ﷺ) said to me: 'A'isha, have you anything (to eat)? I said: 'Messenger of Allah, there is nothing with us. Thereupon he said: I am observing fast. She said: The Messenger of Allah (ﷺ) went out, and there was a present, for us and (at the same time) some visitors dropped in. When the Messenger of Allah (ﷺ) came back, I said to him: Messenger of Allah, a present was given to us, (and in the meanwhile) there came to us visitors (a major Portion of it has been spent on them), but I have saved something for you. He said: What is it? I said: It is hasees (a compound of dates and clarified butter). He said: Bring that. So I brought it to him and he ate it and then said: I woke up in the morning observing fast. Talha said: I narrated this hadith to Mujahid and he said: This (observing of voluntary fast) is like a person who sets apart Sadaqa out of his wealth. He may spend it if he likes, or he may retain it if he so likes.
