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  

"I said to Aishah: 'Did the Messenger of Allah offer Duha prayer? She said: "No, unless he was returning from a journey, I Did the Messenger of Allah fast an entire month?' She said: 'No, I do not remember him fasting any month in full apart from Ramadan, and he did not break his fast for a whole month, rather he would fast some of (each month) until he passed away."' '  

قُلْتُ لِعَائِشَةَ أَكَانَ رَسُولُ اللَّهِ ﷺ يُصَلِّي صَلاَةَ الضُّحَى قَالَتْ لاَ إِلاَّ أَنْ يَجِيءَ مِنْ مَغِيبِهِ قُلْتُ هَلْ كَانَ رَسُولُ اللَّهِ ﷺ يَصُومُ شَهْرًا كُلَّهُ قَالَتْ لاَ مَا عَلِمْتُ صَامَ شَهْرًا كُلَّهُ إِلاَّ رَمَضَانَ وَلاَ أَفْطَرَ حَتَّى يَصُومَ مِنْهُ حَتَّى مَضَى لِسَبِيلِهِ
