بسم الله الرحمن الرحيم
The method of witr salah is that three rakahs of witr salah are offered with one salam. The first two rakahs are performed as normal and after completing tashahhud of the second rakah, one should stand up and after reciting surah in the third rakah should say Allahu Akbar raising the hands up to the ears and folding them below the navel. Thereafter one should recite du’a-e-qunoot; thereafter one should go to ruku saying Allahu Akbar and complete the salah.
Allah knows Best!
