Anas Radiyallahu 'Anhu reports that a tailor invited Rasulullah Sallallahu 'Alayhi Wasallam. Thareed was served, in which dubbaa (dodhi -gourd) was added. As Rasulullah Sallallahu 'Alayhi Wasallam loved dubbaa (dodhi-gourd) he began eating it. Anas Radiyallahu 'Anhu says:
"After that no food was prepared for me, wherein if gourd could be added, it was added"
