Q. I missed the Takbeer of the first rakat in the Eid salah. Should I make sajdah sawoooh or redo the prayer?

A. Insha-Allah, your salaah would be accepted behind the Imaam. The most important thing is that you had not missed any rakats. No sajdah sawhoo need be performed.

Next time, try and be early. (Promptness is virtue.)

Allah certainly knows best.
