How does one make up for a missed Witr and Qiyam prayer after the time for making it up has passed, from Fajr until Zawwal (midday)?

It is sunnah for one who habitually performs the night prayer (Qiyam al-Layl) and Witr to make them up at any time, based on the Prophet's (peace be upon him) saying: "Whoever sleeps through his Witr or forgets it, let him pray it when he remembers it." This is also supported by the action of Aisha (may Allah be pleased with her) who narrated that when the Prophet (peace be upon him) was prevented from performing Qiyam al-Layl due to sleep, pain, or illness, "he would pray twelve rak'ahs during the day."
