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.
