Question: Assalam ‘aleykum
As part of my intention for each makeup prayer, I have been intended to “repeat the last Asr prayer I missed”. Is my intention valid or do I need to be more specific?
Answer: Wa alaikum assalam wa rahmatullah,
Yes, your intention was valid, as were your prayers, because the minimum requirement is specifying a prayer and intending to pray “the last `Asr due,” for instance, fulfils this.
If you can be specific, that is good, yet it is not expressly required of you.
May Allah Most High facilitate all good for you.
