The ruling on following in prayer one who is making up a missed prayer
Machine translationRead the Arabic original
Question:
May Allah reward you. This questioner says: If I miss the congregational prayer and enter the mosque, is it permissible for me to take one of the ma'mums who are making up their prayers as my imam?
Answer:
No. You do not take as your imam the one who is completing his prayer, because he is a ma'mum. A ma'mum does not become an imam except by the imam appointing a substitute in the case of substitution.
