What is the ruling on making up the Sunnah of Fajr and Witr?

Question:
Is the Sunnah of Fajr made up if it is missed, and likewise Witr?

Answer:
Yes, if the Sunnah of Fajr is missed, it is made up after the prayer, or after the sun has risen and become high. This is the Sunnah, and this is what is best.
And so it is with Witr: if it is missed at night, the Sunnah is for the believer, male or female, to pray during the day what he used to pray at night. However, he does not pray Witr; he prays an even number. If he used to pray five, he prays six, with three taslams. If he used to pray three, he says the taslim twice. If he used to pray seven, he prays eight rak'ahs, with four taslams, and so on.
Aisha (may Allah be pleased with her) said: "The Prophet (peace and blessings be upon him), if illness or sleep prevented him from his Witr at night, would pray twelve rak'ahs during the day." And it was the norm for the Prophet (peace and blessings be upon him) to pray eleven rak'ahs at night. So if he was prevented from that by sleep or illness, he would pray them during the day and make them even, praying twelve rak'ahs with six taslims. So likewise, if someone else (peace and blessings be upon him) is prevented from the Witr at night by sleep or illness, he prays during the day, but he makes it even; he does not pray an odd number, he makes it even.
