Prayer: Prioritising That Day's Qadaʾ Prayers
Practical Laws of Islam as per the teachings of Ayatullah Sistani
Ruling 1366
If a person has qaḍāʾ prayers from the past and one or more prayers of that day have also become qaḍāʾ, in the event that he does not have time to make up all of them or he does not want to perform all of them on that day, it is recommended that he make up that day’s qaḍāʾ prayer before he performs the adāʾ prayers.
