Anas bin. Maaik Radiyalahu 'Anhu says:
"A tailor once invited Rasululluh Sallallahu 'Alayhi Wasallam. I also attended the invitation with Rasululluh Sallallahu 'Alayhi Wasallam. He served Rasululluh Sallallahu 'Alayhi Wasallam bread made of barley, and gravy with meat and gourd (dubba-dodhi) in it. I saw Rasululluh Sallallahu 'Alayhi Wasallam look for pieces of gourd from all sides of the plate. From that time I also began loving gourd". (ID)
