Umar’s opinion regarding the slain from the People of Book

The following incident is narrated from Mujahid:

When Umar bin Khattab entered Shaam, he learnt that a Muslim man had slain a person from the People of Book.

So Umar decided to take retaliation from him.

At this point Zaid bin Thabit asked: “Do you want to take retaliation from your brother for the sake of your slave?

So instead of taking retaliation from him, Umar paid him blood money.
