ANSWER:

There’s no such thing as Khatam in taraweeh where you have to finish the whole Qur’an during taraweeh prayers. If the people do it, this is recommended but it is not a must. 

sheikh, is khatam taraweeh an innovation? I mean finishing the Quran through taraweeh or during our prophet’s (saw) time he used to pray such taraweeh? please clarify.
