Answered by Shaykh Yusuf Weltch
Question: Assalamu alaykum
What missed prayers other than the Fard prayers must I make up?
What times am I allowed to make up prayers and how many can I make up at a time?
Answer: In the Name of Allah, the Most Merciful and Compassionate
Prayers that Must Be Made Up
The only prayers that must be made up if missed are the fard (obligatory) prayers and wajib (necessary) prayers, such as the 5 obligatory prayers and the witr prayer. The sunna prayers are not made up.
Permissible Times to Make Up Prayers
It is permissible to make up missed prayers at any time except for the following three times.
(A) After praying the fajr prayer until the sun fully rises.
(B) When the sun is at its zenith just before dhuhr prayer.
(C) After praying the asr prayer until the sun sets.
When making up missed prayers at a permissible time one can pray as many prayers as they wish. However they cannot combine the intention of multiple make up prayers into one prayer.
For example, one cannot pray four units of prayer and intend the three asr prayers that one missed. Rather they must pray each individual prayer on its own.
