Going into Ruk'u' before reading Dua-e-Qunut

Question:

In the third Rak'at of Witr, I went into Ruk'u' before reading Dua-e-Qunut. What should I do to amend my Salah?

Answer:

Continue your Salah normally and perform Sajdah Sahw at the end due to the fact that you missed Dua-e-Qunut. Your Salah will be amended and valid.

Allah takes a life to grant you a thousand lives whereby every life in this new life is better than a thousand lives in the Dunya.
