Machine translationRead the Arabic original
Question:
How does one make up the witr prayer if he missed it?
Answer:
He makes it up during the day, after the sun has risen until just before the midday prayer. All of this time is valid for making it up, but he must make it an even number. He does not pray it as witr during the day; rather, he makes it even. If he usually prays witr with three rak'ahs, he makes it four with two taslims. If he usually prays witr with five, he makes it six, and so on. Yes.
