What is the significance of Durood-e-Ibrahim(as)? Why isn't it common amongst Shias?
Sunnis recite 4 Duroods. What is the significance of those Duroods and can we as Shia also recite them?

In our narrations, it’s highly recommended to send our prayers on Prophet Ibrahim (a) and his family, preceded by sending our prayers on Prophet Muhammad (s) and his family. Prophet Ibrahim (a) was one of Allah’s greatest prophets, and the Ahlulbayt (s) are from his progeny. By remembering Prophet Ibrahim (a), we are reminded that the Ahlulbayt (a) continued his legacy. In Friday sermons, we usually say the Durud of Prophet Ibrahim (a).
