Question:
Honorable Shaykh, may Allah grant you success. He says: I intended to pray the Witr prayer with one rak'ah, but I made a mistake and prayed two rak'ahs, and I did not remember until before the taslim or after it. What is required of me?

Make it an even number and add one rak'ah. Add one rak'ah and consider what happened as an even number. This is better. Yes.
