حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا وَكِيعٌ، عَنْ سُفْيَانَ، عَنِ الْجُرَيْرِيِّ، عَنْ أَبِي السَّلِيلِ، عَنْ أَبِي مُجِيبَةَ الْبَاهِلِيِّ، عَنْ أَبِيهِ، أَوْ عَنْ عَمِّهِ، قَالَ أَتَيْتُ النَّبِيَّ ـ صلى الله عليه وسلم ـ فَقُلْتُ يَا نَبِيَّ اللَّهِ أَنَا الرَّجُلُ الَّذِي أَتَيْتُكَ عَامَ الأَوَّلِ . قَالَ " فَمَا لِي أَرَى جِسْمَكَ نَاحِلاً " . قَالَ يَا رَسُولَ اللَّهِ مَا أَكَلْتُ طَعَامًا بِالنَّهَارِ مَا أَكَلْتُهُ إِلاَّ بِاللَّيْلِ . قَالَ " مَنْ أَمَرَكَ أَنْ تُعَذِّبَ نَفْسَكَ " . قُلْتُ يَا رَسُولَ اللَّهِ إِنِّي أَقْوَى . قَالَ " صُمْ شَهْرَ الصَّبْرِ وَيَوْمًا بَعْدَهُ . قُلْتُ إِنِّي أَقْوَى . قَالَ " صُمْ شَهْرَ الصَّبْرِ وَيَوْمَيْنِ بَعْدَهُ " . قُلْتُ إِنِّي أَقْوَى . قَالَ " صُمْ شَهْرَ الصَّبْرِ وَثَلاَثَةَ أَيَّامٍ بَعْدَهُ وَصُمْ أَشْهُرَ الْحُرُمِ " .
It was narrated from Abu Mujibah Al-Bahili that his father or, his paternal uncle, said:“I came to the Prophet (ﷺ) and said: ‘O Prophet of Allah, I am the man who came to you last year.’ He said: ‘Why do I see your body so thin (and weak)?’ He said: ‘O Messenger of Allah! I do not eat during the day; I only eat at night.’ He said: ‘Who commanded you to punish yourself?’ I said: ‘O Messenger of Allah! I am strong enough.’ He said: ‘Fast the month of patience* and one day after it.’ I said: ‘I am strong enough (to do more).’ He said: ‘Fast the month of patience and two days after it.’ I said: ‘I am strong enough (to do more).’ He said: ‘Fast the month of patience and three days after it, and fast the sacred months.’”
