حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ عَنْ زِيَادِ بْنِ فَيَّاضٍ سَمِعْتُ أَبَا عِيَاضٍ يُحَدِّثُ عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ لَهُ صُمْ يَوْمًا وَلَكَ أَجْرُ مَا بَقِيَ قَالَ إِنِّي أُطِيقُ أَكْثَرَ مِنْ ذَلِكَ قَالَ صُمْ يَوْمَيْنِ وَلَكَ أَجْرُ مَا بَقِيَ قَالَ إِنِّي أُطِيقُ أَكْثَرَ مِنْ ذَلِكَ قَالَ صُمْ ثَلَاثَةَ أَيَّامٍ وَلَكَ أَجْرُ مَا بَقِيَ قَالَ إِنِّي أُطِيقُ أَكْثَرَ مِنْ ذَلِكَ قَالَ صُمْ أَرْبَعَةَ أَيَّامٍ وَلَكَ أَجْرُ مَا بَقِيَ قَالَ إِنِّي أُطِيقُ أَكْثَرَ مِنْ ذَلِكَ قَالَ صُمْ أَفْضَلَ الصِّيَامِ عِنْدَ اللَّهِ صُمْ صَوْمَ دَاوُدَ كَانَ يَصُومُ يَوْمًا وَيُفْطِرُ يَوْمًا.
English Translation
Muhammad ibn Ja'far told us: Shu'bah told us, from Ziyad ibn Fayyad: I heard Abu Iyad narrating from Abdullah ibn Amr, that the Prophet, peace and blessings be upon him, said to him: Fast one day and you shall have the reward of what remains. He said: I am able to do more than that. He said: Fast two days and you shall have the reward of what remains. He said: I am able to do more than that. He said: Fast three days and you shall have the reward of what remains. He said: I am able to do more than that. He said: Fast four days and you shall have the reward of what remains. He said: I am able to do more than that. He said: Fast the most excellent fast in Allah's sight - fast the fast of Dawud, who used to fast a day and break his fast a day.
