Arabic (Original)
حَدَّثَنَا عَفَّانُ حَدَّثَنَا أَبُو عَوَانَةَ حَدَّثَنَا عَبْدُ الْمَلِكِ بْنُ عُمَيْرٍ عَنْ مُوسَى بْنِ طَلْحَةَ عَنْ أَبِي هُرَيْرَةَ قَالَ أَتَى أَعْرَابِيٌّ إِلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِأَرْنَبٍ قَدْ شَوَاهَا وَمَعَهَا صِنَابُهَا وَأُدُمُهَا فَوَضَعَهَا بَيْنَ يَدَيْهِ فَأَمْسَكَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَلَمْ يَأْكُلْ وَأَمَرَ أَصْحَابَهُ أَنْ يَأْكُلُوا فَأَمْسَكَ الْأَعْرَابِيُّ فَقَالَ لَهُ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَا يَمْنَعُكَ أَنْ تَأْكُلَ قَالَ إِنِّي أَصُومُ ثَلَاثَةَ أَيَّامٍ مِنْ الشَّهْرِ قَالَ إِنْ كُنْتَ صَائِمًا فَصُمْ أَيَّامَ الْغُرِّ.
English Translation
A Bedouin came to the Messenger of Allah (peace be upon him) with a roasted rabbit along with its condiment and sauce. He placed it before him, but the Messenger of Allah (peace be upon him) refrained and did not eat, though he told his companions to eat. The Bedouin also refrained, so the Messenger of Allah (peace be upon him) said to him: "What prevents you from eating?" He said: "I fast three days of every month." He said: "If you are going to fast, then fast the bright days (the 13th, 14th, and 15th of the lunar month)."
