It shows that he was steadfast and supporter of justice. Abu Lulu Feroze, his murderer had asked for an unfair concession which was against justice. He said to Hazrat Umar that his master, Mughira B. Shuba charged him 2 dirhams per day which was hard for him to earn, indeed, if Lulu had worked harder, it was easy to earn 2 dirhams. That is why Hazrat Umar refused his claim and this lead to his death.
