Making up the missed Witr prayer

Question:
The questioner asks: How does one make up the Witr if he missed it? And if one leaves off the Witr and is content with the obligatory prayers, is that accepted from him?

Answer:
The Witr is a confirmed Sunnah (recommended practice), and the Messenger (peace and blessings be upon him) urged it. It is a confirmed Sunnah, and a Muslim does not leave it off; rather, he maintains the Witr as the Prophet (peace and blessings be upon him) commanded. He said: . In fact, some scholars hold that the Witr is obligatory, but the majority hold that it is a confirmed Sunnah. Some of the Imams even hold that a person’s integrity is lost if he is negligent with the Witr and leaves it off, as mentioned in this question: his testimony is not accepted. The matter here is serious. If he leaves it off for some nights because he slept through it or was preoccupied with it, he makes it up during the day and pairs it. If he used to pray the Witr with three rak'ahs, he makes it four with two taslims (closing salams). If he used to pray the Witr with five, he makes it six with three taslims. And so the Prophet (peace and blessings be upon him), if he missed the Witr at night, would make it up during the day. He used to pray the Witr with eleven rak'ahs, and he would make it up during the day with twelve rak'ahs.
