[Machine] I came to the Messenger of Allah and said, "O Messenger of Allah, I am the man who came to you first." He said, "Why do I not see you looking thin?" I said, "O Messenger of Allah, I have not eaten any food during the day since I pledged allegiance to you." He said, "Who told you to torture yourself?" I said, "O Messenger of Allah, I am strong." He said, "Fast the month of patience and two days after it." I said, "I am strong." He said, "Fast the month of patience and three days after it, and fast the sacred months."  

الطبراني:١٩١٩٥ – حَدَّثَنَا عُبَيْدُ بْنُ غَنَّامٍ ثنا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ ثنا وَكِيعٌ عَنْ سُفْيَانَ عَنِ الْجُرَيْرِيِّ عَنْ أَبِي السَّلِيلِ عَنْ مُجِيبَةَ عَنْ أَبِيهِ أَوْ عَمِّهِ قَالَ

أَتَيْتُ رَسُولَ اللهِ ﷺ فَقُلْتُ يَا رَسُولَ اللهِ أَنَا الرَّجُلُ الَّذِي جِئْتُكَ عَامَ أَوَّلَ قَالَ «فَمَا لِي أَرَى جِسْمَكَ نَاحِلًا» قُلْتُ يَا رَسُولَ اللهِ مَا أَكَلْتُ طَعَامًا بِنَهَارٍ مُنْذُ بَايَعْتُكَ فَقَالَ «مَنْ أَمَرَكَ أَنْ تُعَذِّبَ نَفْسَكَ؟» قُلْتُ يَا رَسُولَ اللهِ إِنِّي أَقْوَى قَالَ «صُمْ شَهْرَ الصَّبْرِ وَيَوْمَيْنِ بَعْدَهُ» قُلْتُ إِنِّي أَقْوَى قَالَ «صُمْ شَهْرَ الصَّبْرِ وَثَلَاثَةَ أَيَّامٍ بَعْدَهُ وَصُمْ أَشْهُرَ الْحُرُمِ»

“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.’”
