It is narrated from Hazrat Asma bin Rabee. He says that we presented ourselves before Hazrat Umar. We were some people whose condition was very good. He states that Hazrat Umar asked: What is your food? We said: Dabb (a type of lizard). The narrator says: Upon this, Hazrat Umar said: Does it suffice you? We said: Yes! Upon this, he said: I like that with every dabb there should be another like it (i.e., another dabb).
