A man prayed the tarawih and left before the imam’s witr!

Question:
We have another caller. Honorable Shaykh, yes, Honorable Shaykh, some people pray the tarawih with us, but before the shaf' and the witr, they leave and abandon the shaf' and the witr.

Answer:
This is contrary to the Sunnah. The Prophet (peace and blessings be upon him) said: So one should not leave until the imam leaves, if he wants the complete reward from Allah the Exalted. And if he wants to stand in prayer at the end of the night, he may stand.
Even after he has prayed the witr with the imam, he may stand, but he does not repeat the witr a second time; the first witr is sufficient. Because some people may leave the imam, saying, "I have a prayer at the end of the night; I want to keep the witr for the end of the night." This is contrary to what is best. The best is that he stays with the imam until he leaves and prays the witr with the imam. And if he stands at the end of the night, he does not need another witr. Yes. He prays two rak'ahs, two rak'ahs. The prayer of the night and the day is in pairs, two by two. Yes.
