عَنْ أَنَسٍ قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُفْطِرُ مِنَ الشَّهْرِ حَتَّى يُظَنَّ أَنْ لَا يَصُومَ مِنْهُ وَيَصُومُ حَتَّى يُظَنَّ أَنْ لَا يُفْطِرَ مِنْهُ شَيْئًا وَكَانَ لَا تَشَاءُ أَنْ تَرَاهُ مِنَ اللَّيْلِ مُصَلِّيًا إِلَّا رَأَيْتَهُ وَلَا نَائِمًا إِلَّا رَأَيْتَهُ. رَوَاهُ البُخَارِيّ

Anas said: The Messenger of God, peace and blessings be upon him, would go through a month without fasting until we thought he would not fast any of it; and he would fast until we thought he would not break his fast at all during it. Whenever one wished to see him praying at night, one saw him; and whenever one wished to see him sleeping, one saw him. Al-Bukhari transmitted it.
