This hadith has been narrated by Ja'far with the some chain of trans- mitters and he added: It was said to him (to the Holy Prophet): There are people to whom fasting has become unbearable and they are waiting how you do. He (the Holy Prophet) then called for a cup of water when it was afternoon. The rest of the hadith is the same.
وَحَدَّثَنَاهُ قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا عَبْدُ الْعَزِيزِ، - يَعْنِي الدَّرَاوَرْدِيَّ - عَنْ جَعْفَرٍ، بِهَذَا الإِسْنَادِ وَزَادَ فَقِيلَ لَهُ إِنَّ النَّاسَ قَدْ شَقَّ عَلَيْهِمُ الصِّيَامُ وَإِنَّمَا يَنْظُرُونَ فِيمَا فَعَلْتَ . فَدَعَا بِقَدَحٍ مِنْ مَاءٍ بَعْدَ الْعَصْرِ .
