ذِكْرُ الْإِبَاحَةِ لِلْمَرْءِ أَنْ يُنْشِئَ الصَّوْمَ التَّطَوُّعَ بِالنَّهَارِ، وَإِنْ لَمْ يَكُنْ تَقَدَّمَ الْعَزْمُ لَهُ مِنَ اللَّيْلِ مِنْهُ

The Apostle of Allah ﷺ came to me one day and said: Is there anything with you (to eat)? I said: No. Thereupon he said: I shall then be fasting. Then he came to us another day and we said: Messenger of Allah, hais has been offered to us as a gift. Thereupon he said: Show that to me; I had been fasting since morning. He then ate it.  

دَخَلَ عَلَىَّ النَّبِيُّ ﷺ ذَاتَ يَوْمٍ فَقَالَ هَلْ عِنْدَكُمْ شَىْءٌ فَقُلْنَا لاَ قَالَ فَإِنِّي إِذًا صَائِمٌ ثُمَّ أَتَانَا يَوْمًا آخَرَ فَقُلْنَا يَا رَسُولَ اللَّهِ أُهْدِيَ لَنَا حَيْسٌ فَقَالَ أَرِينِيهِ فَلَقَدْ أَصْبَحْتُ صَائِمًا فَأَكَلَ  

When the Prophet ﷺ entered upon me, he would ask: Do you have food ? When we said: No, he would say: I am fasting. Waki' added in his version: Another day when he entered upon us, we said: Messenger of Allah, some pudding (hair) has been presented to us and we have retained it for you. He said: Bring it to me. Talhah said: He fasted in the morning, but broke his fast (that day).  

كَانَ رَسُولُ اللَّهِ ﷺ إِذَا دَخَلَ عَلَىَّ قَالَ هَلْ عِنْدَكُمْ طَعَامٌ فَإِذَا قُلْنَا لاَ قَالَ إِنِّي صَائِمٌ زَادَ وَكِيعٌ فَدَخَلَ عَلَيْنَا يَوْمًا آخَرَ فَقُلْنَا يَا رَسُولَ اللَّهِ أُهْدِيَ لَنَا حَيْسٌ فَحَبَسْنَاهُ لَكَ فَقَالَ أَدْنِيهِ قَالَ طَلْحَةُ فَأَصْبَحَ صَائِمًا وَأَفْطَرَ
