(4) باب مَنْ تَتَبَّعَ حَوَالَىِ الْقَصْعَةِ مَعَ صَاحِبِهِ، إِذَا لَمْ يَعْرِفْ مِنْهُ كَرَاهِيَةً
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."
