Narrated Anas bin Malik:

A tailor invited Allah's Messenger (ﷺ) to a meal which he had prepared. I went along with Allah's Messenger (ﷺ) and saw him seeking to eat the pieces of gourd from the various sides of the dish. Since that day I have liked to eat gourd. `Umar bin Abi Salama said: The Prophet, said to me, "Eat with your right hand."

حَدَّثَنَا قُتَيْبَةُ، عَنْ مَالِكٍ، عَنْ إِسْحَاقَ بْنِ أَبِي طَلْحَةَ، أَنَّهُ سَمِعَ أَنَسَ بْنَ مَالِكٍ، يَقُولُ إِنَّ خَيَّاطًا دَعَا رَسُولَ اللَّهِ صلى الله عليه وسلم لِطَعَامٍ صَنَعَهُ ـ قَالَ أَنَسٌ ـ فَذَهَبْتُ مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم فَرَأَيْتُهُ يَتَتَبَّعُ الدُّبَّاءَ مِنْ حَوَالَىِ الْقَصْعَةِ ـ قَالَ ـ فَلَمْ أَزَلْ أُحِبُّ الدُّبَّاءَ مِنْ يَوْمِئِذٍ‏.‏
