Is it better to consistently recite Surah al-A'la, Surah al-Kafirun, and Surah al-Ikhlas in the Witr prayer, or is it better to sometimes omit them?

Question:
He says: Honorable Shaykh, may Allah grant you success, which is better: to consistently recite these three surahs—al-A'la, al-Kafirun, and al-Ikhlas—in the Witr prayer, or is it better to do so sometimes and omit them other times?

Answer:
By Allah, it is better to be consistent with them. It is better to be consistent with them, as the Prophet (peace and blessings be upon him) used to do so. Yes. But if he omits them some of the time, there is nothing wrong with that. Especially if he wants to teach people that they are not obligatory. Yes.
