أَخْبَرَنَا أَحْمَدُ بْنُ إِسْحَاقَ بْنِ بُهْلُولٍ ، ثنا أَبُو سَعِيدٍ الأَشَجُّ ، ثنا أَبُو خَالِدٍ الأَحْمَرُ سُلَيْمَانُ بْنُ حَيَّانَ ، عَنْ عَمْرِو بْنِ قَيْسٍ ، عَنْ أَبِي إِسْحَاقَ ، عَنْ صِلَةَ ، قَالَ : كُنَّا عِنْدَ عَمَّارٍ فَأُتِيَ بِشَاةٍ مَصْلِيَّةٍ ، فَقَالَ " كُلُوا " ، فَتَنَحَّى بَعْضُ الْقَوْمِ ، فَقَالَ : إِنِّي صَائِمٌ ، فَقَالَ عَمَّارٌ : " مَنْ صَامَ الْيَوْمَ الَّذِي شَكَّ فِيهِ فَقَدْ عَصَى أَبَا الْقَاسِمِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ " . هَذَا إِسْنَادٌ حَسَنٌ صَحِيحٌ ، وَرُوَاتُهُ كُلُّهُمْ ثِقَاتٌ.
Sila narrates: We were present with Sayyiduna Ammar (may Allah be pleased with him) when roasted goat meat was brought for him, and he told us to eat. One person withdrew, so he (Ammar) said: "Whoever fasts on the day when there is doubt about (the beginning of) Ramadan, he has disobeyed Sayyiduna Abu al-Qasim (the Prophet Muhammad, peace and blessings be upon him)." This hadith is Hasan Sahih, and all the narrators of this hadith are trustworthy.
