Hadith 31

Sahih Bukhari

Book 30: Fasting

Chapter 20

Sahur is a blessing but it is not compulsory

باب بَرَكَةِ السَّحُورِ مِنْ غَيْرِ إِيجَابٍ

For the Prophet ﷺ and his companions kept observing fasting continuously for more than one day and (of course) no Sahur (late night meals) was taken (during that prolonged fast).
لأَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَأَصْحَابَهُ وَاصَلُوا وَلَمْ يُذْكَرِ السَّحُورُ.
Sahih al-Bukhari 1922
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا جُوَيْرِيَةُ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ أَنَّ النَّبِيَّ صلى الله عليه وسلم وَاصَلَ فَوَاصَلَ النَّاسُ فَشَقَّ عَلَيْهِمْ، فَنَهَاهُمْ‏.‏ قَالُوا إِنَّكَ تُوَاصِلُ‏.‏ قَالَ ‏ ‏‏.‏
"‏ لَسْتُ كَهَيْئَتِكُمْ، إِنِّي أَظَلُّ أُطْعَمُ وَأُسْقَى ‏"
`Abdullah:

The Prophet (ﷺ) fasted for days continuously; the people also did the same but it was difficult for them. So, the Prophet (ﷺ) forbade them (to fast continuously for more than one day). They slid, "But you fast without break (no food was taken in the evening or in the morning)." The Prophet (ﷺ) replied, "I am not like you, for I am provided with food and drink (by Allah).
