"The Messenger of Allah said: 'Eat Sahur, for in Sahur there is blessing." (Hasan) Abu 'Abdur-Rahman (An-Nasai) said: In this narration of Yahya bin Saeed, its chain is Hasan but it is Munkar, and I fear that the error is from Muhammad bin Fudail. (Using translation from Nasāʾī 2151)
قَالَ رَسُولُ اللهِ ﷺ «تَسَحَّرُوا فَإِنَّ فِي السَّحُورِ بَرَكَةً» قَالَ أَبُو عَبْدِ الرَّحْمَنِ حَدِيثُ يَحْيَى بْنِ سَعِيدٍ هَذَا إِسْنَادُهُ حَسَنٌ وَهُوَ مُنْكَرٌ وَأَخَافُ أَنْ يَكُونَ الْغَلَطُ مِنْ مُحَمَّدِ بْنِ فُضَيْلٍ
