Sahih Bukhari, Chapter: Sales and Trade

I heard Anas bin Malik saying, "A tailor invited Allah's Apostle to a meal which he had prepared. " Anas bin Malik said, "I accompanied Allah's Apostle to that meal. He served the Prophet with bread and soup made with gourd and dried meat. I saw the Prophet taking the pieces of gourd from the dish." Anas added, "Since that day I have continued to like gourd."
