Is the reward for standing in night prayer written for one who prepared and got ready to stand but then fell asleep and did not wake up?

Question : Our Shaykh, on a day when a person intends to set the time, for example, to before Fajr, Allah is the best disposer of affairs.

Answer : Yes, if it is a person's habit to stand in prayer at night, and then he prepares and mounts his mount at the time he intends, but he does not stand in prayer, he is recorded as having the reward. However, he should complete that by making up the missed prayer. The Prophet (peace and blessings be upon him) used to perform the witr, but he made the witr an even number. It was his habit, and this was the case for most of his life (peace and blessings be upon him), to perform the witr with eleven rak'ahs. So if the night passed and he had not performed the witr at night, he would pray twelve rak'ahs.
