حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا شُعْبَةُ، عَنْ أَنَسِ بْنِ سِيرِينَ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ قَالَ رَجُلٌ مِنَ الأَنْصَارِ يَا رَسُولَ اللَّهِ إِنِّي رَجُلٌ ضَخْمٌ - وَكَانَ ضَخْمًا - لاَ أَسْتَطِيعُ أَنْ أُصَلِّيَ مَعَكَ -وَصَنَعَ لَهُ طَعَامًا وَدَعَاهُ إِلَى بَيْتِهِ - فَصَلِّ حَتَّى أَرَاكَ كَيْفَ تُصَلِّي فَأَقْتَدِيَ بِكَ ‏.‏ فَنَضَحُوا لَهُ طَرَفَ حَصِيرٍ كَانَ لَهُمْ فَقَامَ فَصَلَّى رَكْعَتَيْنِ ‏.‏قَالَ فُلاَنُ بْنُ الْجَارُودِ لأَنَسِ بْنِ مَالِكٍ أَكَانَ يُصَلِّي الضُّحَى قَالَ لَمْ أَرَهُ صَلَّى إِلاَّ يَوْمَئِذٍ
Translation
Anas b. Malik reported

A man from the Ansar said: "O Messenger of Allah, indeed I am a heavy man" - and he was heavy - "and I cannot pray with you." And he prepared food for him and invited him to his house. (He said): "So pray until I see you, how you pray, so that I may follow you." So they sprinkled water on a side of a mat belonging to them, and he stood up and prayed two rak'ahs.

Fulan ibn al-Jarud said to Anas ibn Malik: "Did he pray the duha prayer?" He said: "I did not see him pray except on that day."
