Q. What Surahs should one recite in the three Rakaats of Witr Salaah?
A. It is Sunnah to recite Surah A’ala in the first Rakaat, Surah Kaafiroon in the second Rakaat and Surah Ikhlaas in the third Rakaat of Witr Salaah. However, the recital of these surahs should not be fixed on a daily basis for Witr Salaah as people may consider reciting these Surahs to be necessary for Witr Salaah. One should recite these Surahs occasionally without fixing it. (Shaami 2/6)
