I said to 'A'isha (Allah be pleased with her): Did the Messenger of Allah ﷺ observe fast during a month? She said, I do not know of any month in which he fasted throughout except Ramadan and (the month) in which he did not fast at all till he ran the course of his life. May peace be upon him.  

قُلْتُ لِعَائِشَةَ ؓ أَكَانَ رَسُولُ اللَّهِ ﷺ يَصُومُ شَهْرًا كُلَّهُ قَالَتْ مَا عَلِمْتُهُ صَامَ شَهْرًا كُلَّهُ إِلاَّ رَمَضَانَ وَلاَ أَفْطَرَهُ كُلَّهُ حَتَّى يَصُومَ مِنْهُ حَتَّى مَضَى لِسَبِيلِهِ ﷺ  

[Machine] About the fasting of the Messenger of Allah ﷺ ? She said, "I did not know that he fasted for a whole month continuously, nor did he break his fast for a whole month continuously, until he departed for his journey."  

عَنْ صَوْمِ رَسُولِ اللهِ ﷺ؟ فَقَالَتْ مَا عَلِمْتُهُ صَامَ شَهْرًا حَتَّى يُفْطِرَ مِنْهُ وَلَا أَفْطَرَ حَتَّى يَصُومَ مِنْهُ حَتَّى مَضَى لِسَبِيلِهِ  

[Machine] I asked Aisha if the Messenger of Allah ﷺ used to fast the entire month. She said, "I do not know of him fasting the entire month except for Ramadan. And he would not break his fast for the entire month until he had fasted from it until the next month's moon was visible, or until he departed."  

سَأَلْتُ عَائِشَةَ أَكَانَ رَسُولُ اللهِ ﷺ يَصُومُ شَهْرًا كُلَّهُ؟ قَالَتْ مَا عَلِمْتُهُ صَامَ شَهْرًا كُلَّهُ حَتَّى يُفْطِرَ مِنْهُ إِلَّا رَمَضَانَ وَلَا أَفْطَرَ شَهْرًا كُلَّهُ حَتَّى يَصُومَ مِنْهُ حَتَّى مَضَى لِوَجْهِهِ أَوْ لِسَبِيلِهِ ﷺ
