Is the greeting of the mosque sufficient with one rak'ah?

Question:
Honorable Shaykh, the questioner asks: Is the greeting of the mosque at night sufficient with one rak'ah instead of two?

Answer:
The greeting of the mosque is two rak'ahs, as the Prophet (peace and blessings be upon him) commanded: "Stand up and pray two rak'ahs, and do not sit until you have prayed two rak'ahs." So we do not settle for one rak'ah. This is regarding the witr; this is regarding the witr. The minimum for the witr is one rak'ah. Yes. Some scholars say that even a voluntary prayer is sufficient with one rak'ah, but the evidence from the Sunnah indicates that one rak'ah is only sufficient for the witr. Yes.
