Full Sharh — Sahih al-Bukhari 1179
حَدَّثَنَا عَلِيُّ بْنُ الْجَعْدِ، أَخْبَرَنَا شُعْبَةُ، عَنْ أَنَسِ بْنِ سِيرِينَ، قَالَ سَمِعْتُ أَنَسَ بْنَ مَالِكٍ الأَنْصَارِيَّ، قَالَ قَالَ رَجُلٌ مِنَ الأَنْصَارِ ـ وَكَانَ ضَخْمًا ـ لِلنَّبِيِّ صلى الله عليه وسلم إِنِّي لاَ أَسْتَطِيعُ الصَّلاَةَ مَعَكَ. فَصَنَعَ لِلنَّبِيِّ صلى الله عليه وسلم طَعَامًا، فَدَعَاهُ إِلَى بَيْتِهِ، وَنَضَحَ لَهُ طَرَفَ حَصِيرٍ بِمَاءٍ فَصَلَّى عَلَيْهِ رَكْعَتَيْنِ. وَقَالَ فُلاَنُ بْنُ فُلاَنِ بْنِ جَارُودٍ لأَنَسٍ ـ رضى الله عنه ـ أَكَانَ النَّبِيُّ صلى الله عليه وسلم يُصَلِّي الضُّحَى فَقَالَ مَا رَأَيْتُهُ صَلَّى غَيْرَ ذَلِكَ الْيَوْمِ.
