Chapter 42 | The Case of One Who Wakes up in the Morning with an Intention to Fast, but Who Does Not Do So or Vice Versa when Fasting Is a Compensatory Fast for the Missed Fast in the Month of Ramadan or Other Days
1ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادِ بْنِ عُثْمَانَ عَنِ الْحَلَبِيِّ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) قَالَ سَأَلْتُهُ عَنِ الرَّجُلِ يُصْبِحُ وَهُوَ يُرِيدُ الصِّيَامَ ثُمَّ يَبْدُو لَهُ فَيُفْطِرُ قَالَ هُوَ بِالْخِيَارِ مَا بَيْنَهُ وَبَيْنَ نِصْفِ النَّهَارِ قُلْتُ هَلْ يَقْضِيهِ إِذَا أَفْطَرَ قَالَ نَعَمْ لأَنَّهَا حَسَنَةٌ أَرَادَ أَنْ يَعْمَلَهَا فَلْيُتِمَّهَا قُلْتُ فَإِنَّ رَجُلاً أَرَادَ أَنْ يَصُومَ ارْتِفَاعَ النَّهَارِ أَ يَصُومُ قَالَ نَعَمْ.
1. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Hammad ibn ‘Uthaman from al-Halabiy who has said the following: “This is concerning my question before abu ‘ Abd Allah , about a man who with the intention to fast wakes up in the morning, then for a certain reason decides not to fast. He (the Imam) said, ‘Until midday it is his choice to fast or not to fast.’ I then asked, ‘Is he required to make Qada’ (compensatory fast) for such fast if he discontinues it?’ He (the Imam) said, ‘Yes, it is a valid deed that he intended to do and he should complete it.’ I then asked, ‘Can a man who, when the day is up, decide to fast, do so?’ He (the Imam) said, ‘Yes, it is permissible for him to do so.’”
