Hadith 4754ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ وَمُحَمَّدُ بْنُ إِسْمَاعِيلَ عَنِ الْفَضْلِ بْنِ شَاذَانَ جَمِيعاً عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْحَجَّاجِ عَنْ أَبِي الْحَسَنِ صَلَوَاتُ الله عَلَيْهِ فِي الرَّجُلِ يَبْدُو لَهُ بَعْدَ مَا يُصْبِحُ وَيَرْتَفِعُ النَّهَارُ فِي صَوْمِ ذَلِكَ الْيَوْمِ لِيَقْضِيَهُ مِنْ شَهْرِ رَمَضَانَ وَلَمْ يَكُنْ نَوَى ذَلِكَ مِنَ اللَّيْلِ قَالَ نَعَمْ لِيَصُمْهُ وَلْيَعْتَدَّ بِهِ إِذَا لَمْ يَكُنْ أَحْدَثَ شَيْئاً.

He did not have such intention in the night. Abu al-Hassan (a.s.), has said that he can fast that day and count it, if nothing invalidating has taken place before.”
