Messenger of Allah ﷺ used to fast till one would say that he would never stop fasting, and he would abandon fasting till one would say that he would never fast. I never saw Messenger of Allah ﷺ fasting for a whole month except the month of Ramadan, and did not see him fasting in any month more than in the month of Sha'ban.  

كَانَ رَسُولُ اللَّهِ ﷺ يَصُومُ حَتَّى نَقُولَ لاَ يُفْطِرُ وَيُفْطِرُ حَتَّى نَقُولَ لاَ يَصُومُ فَمَا رَأَيْتُ رَسُولَ اللَّهِ ﷺ اسْتَكْمَلَ صِيَامَ شَهْرٍ إِلاَّ رَمَضَانَ وَمَا رَأَيْتُهُ أَكْثَرَ صِيَامًا مِنْهُ فِي شَعْبَانَ  

I asked 'A'isha (Allah be pleased with her) about the fasting of the Messenger of Allah ﷺ. She said: He used to observe fast (at times so continuously) that we said: He has fasted (never to break), and he did not observe fast till we said: He has given up perhaps never to fast, and I never saw him observing (voluntary fasts) more in any other month than that of Sha'ban. (lt appeared as if) he observed fast throughout the whole of Sha'ban except a few (days).  

عَنْ صِيَامِ رَسُولِ اللَّهِ ﷺ فَقَالَتْ كَانَ يَصُومُ حَتَّى نَقُولَ قَدْ صَامَ وَيُفْطِرُ حَتَّى نَقُولَ قَدْ أَفْطَرَ وَلَمْ أَرَهُ صَائِمًا مِنْ شَهْرٍ قَطُّ أَكْثَرَ مِنْ صِيَامِهِ مِنْ شَعْبَانَ كَانَ يَصُومُ شَعْبَانَ كُلَّهُ كَانَ يَصُومُ شَعْبَانَ إِلاَّ قَلِيلاً  

"I asked Aishah: 'Tell me about the fasting of the Messenger of Allah.' She said: 'he used to fast until we said: he is going to fast until we said: He is not going to fast. He never fasted any month more than Shaban. He used to fast (all) of Shaban except a little, he used to fast all of Shaban."' '  

عَنْ صِيَامِ رَسُولِ اللَّهِ ﷺ قَالَتْ كَانَ يَصُومُ حَتَّى نَقُولَ قَدْ صَامَ وَيُفْطِرُ حَتَّى نَقُولَ قَدْ أَفْطَرَ وَلَمْ يَكُنْ يَصُومُ شَهْرًا أَكْثَرَ مِنْ شَعْبَانَ كَانَ يَصُومُ شَعْبَانَ إِلاَّ قَلِيلاً كَانَ يَصُومُ شَعْبَانَ كُلَّهُ  

“I asked ‘Aishah about the fasting of the Prophet ﷺ. She said: ‘He used to fast until we thought he would always fast. And he used to not fast until we thought he would always not fast. I never saw him fast more in any month than in Sha’ban. He used to fast all of Sha’ban; he used to fast all of Sha’ban except a little.’”  

عَنْ صِيَامِ النَّبِيِّ ﷺ فَقَالَتْ كَانَ يَصُومُ حَتَّى نَقُولَ قَدْ صَامَ وَيُفْطِرُ حَتَّى نَقُولَ قَدْ أَفْطَرَ وَلَمْ أَرَهُ صَامَ مِنْ شَهْرٍ قَطُّ أَكْثَرَ مِنْ صِيَامِهِ مِنْ شَعْبَانَ كَانَ يَصُومُ شَعْبَانَ كُلَّهُ كَانَ يَصُومُ شَعْبَانَ إِلاَّ قَلِيلاً  

Yahya related to me from Malik from Abu'n Nadr, the mawla of Umar ibn Ubaydullah, from Abu Salama ibn Abd ar-Rahman that A'isha, the wife of the Prophet ﷺ said, "The Messenger of Allah ﷺ used to fast for so long that we thought he would never stop fasting, and he would go without fasting for so long that we thought he would never fast again. I never saw the Messenger of Allah ﷺ fast for a complete month except for Ramadan, and I never saw him do more fasting in any one month than he did in Shaban.'  

عَنْ عَائِشَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّهَا قَالَتْ كَانَ رَسُولُ اللَّهِ ﷺ يَصُومُ حَتَّى نَقُولَ لاَ يُفْطِرُ وَيُفْطِرُ حَتَّى نَقُولَ لاَ يَصُومُ وَمَا رَأَيْتُ رَسُولَ اللَّهِ ﷺ اسْتَكْمَلَ صِيَامَ شَهْرٍ قَطُّ إِلاَّ رَمَضَانَ وَمَا رَأَيْتُهُ فِي شَهْرٍ أَكْثَرَ صِيَامًا مِنْهُ فِي شَعْبَانَ  

The Messenger of Allah ﷺ used to fast to such an extent that we thought that he would never break his fast, and he would go without fasting to such an extent that we thought he would never fast. I never saw the Messenger of Allah ﷺ fast a complete month except in Ramadan, and I never saw his fast more in any month than in Sha'ban. (Using translation from Abū Dāʾūd 2434)  

أَنَّهَا قَالَتْ كَانَ رَسُولُ اللهِ ﷺ يَصُومُ حَتَّى نَقُولَ لَا يُفْطِرُ وَيُفْطِرُ حَتَّى نَقُولَ لَا يَصُومُ وَمَا رَأَيْتُ رَسُولَ اللهِ ﷺ اسْتَكْمَلَ صِيَامَ شَهْرٍ قَطُّ إِلَّا رَمَضَانَ وَمَا رَأَيْتُهُ فِي شَهْرٍ قَطُّ أَكْثَرَ صِيَامًا مِنْهُ فِي شَعْبَانَ  

The Messenger of Allah ﷺ used to fast to such an extent that we thought that he would never break his fast, and he would go without fasting to such an extent that we thought he would never fast. I never saw the Messenger of Allah ﷺ fast a complete month except in Ramadan, and I never saw his fast more in any month than in Sha'ban. (Using translation from Abū Dāʾūd 2434)   

كَانَ رَسُولُ اللهِ ﷺ يَصُومُ حَتَّى نَقُولَ لَا يُفْطِرُ وَيُفْطِرُ حَتَّى نَقُولَ لَا يَصُومُ وَمَا اسْتَكْمَلَ صِيَامَ شَهْرٍ قَطُّ إِلَّا رَمَضَانَ وَمَا رَأَيْتُهُ فِي شَهْرٍ قَطُّ أَكْثَرَ صِيَامًا مِنْهُ فِي شَعْبَانَ  

[Machine] I asked, "What was the fasting of the Messenger of Allah ﷺ like?"

She said, "He used to fast until we would say that he would not break his fast, and he would break his fast until we would say that he would not fast. I never saw him fast more in any month than he did in Sha'ban. He used to fast in Sha'ban except for a little, or rather, he used to fast the entire month."  

قُلْتُ أَيْ أُمَّهْ كَيْفَ كَانَ صِيَامُ رَسُولِ اللهِ ﷺ؟ قَالَتْ كَانَ يَصُومُ حَتَّى نَقُولَ لَا يُفْطِرُ وَيُفْطِرُ حَتَّى نَقُولَ لَا يَصُومُ وَلَمْ أَرَهُ يَصُومُ مِنْ شَهْرٍ أَكْثَرَ مِنْ صِيَامِهِ مِنْ شَعْبَانَ كَانَ يَصُومُ شَعْبَانَ إِلَّا قَلِيلًا بَلْ كَانَ يَصُومُهُ كُلَّهُ  

Messenger of Allah ﷺ used to fast till one would say that he would never stop fasting, and he would abandon fasting till one would say that he would never fast. I never saw Messenger of Allah ﷺ fasting for a whole month except the month of Ramadan, and did not see him fasting in any month more than in the month of Sha'ban. (Using translation from Bukhārī 1969)  

«كَانَ رَسُولُ اللَّهِ ﷺ يَصُومُ حَتَّى نَقُولَ لَا يُفْطِرُ وَيُفْطِرُ حَتَّى نَقُولَ لَا يَصُومُ وَمَا رَأَيْتُ رَسُولَ اللَّهِ ﷺ اسْتَكْمَلَ صِيَامَ شَهْرٍ قَطُّ إِلَّا رَمَضَانَ وَمَا رَأَيْتُهُ أَكْثَرَ صِيَامًا مِنْهُ فِي شَعْبَانَ»  

"I asked Aishah: 'Tell me about the fasting of the Messenger of Allah.' She said: 'he used to fast until we said: he is going to fast until we said: He is not going to fast. He never fasted any month more than Shaban. He used to fast (all) of Shaban except a little, he used to fast all of Shaban."' ' (Using translation from Nasāʾī 2179)   

كَانَ رَسُولُ اللهِ ﷺ يَصُومُ حَتَّى نَقُولَ لَا يُفْطِرُ وَيُفْطِرُ حَتَّى نَقُولَ لَا يَصُومُ وَلَمْ أَرَهُ فِي شَهْرٍ أَكْثَرَ مِنْهُ صِيَامًا فِي شَعْبَانَ كَانَ يَصُومُ شَعْبَانَ إِلَّا قَلِيلًا بَلْ كَانَ يَصُومُ شَعْبَانَ كُلَّهُ
