Musaafir mistakenly performing 4 rakaats Zuhr Salaah while leading a congregation for an entire week
Q: If a musaafir mistakenly leads a congregation in Zuhr Salaah for an entire week whilst performing 4 rakaats, and only realizes after that, then what is the status of the other musaafirs' Salaahs - those who performed salaah behind such an Imam?
Will their Salaah be valid/complete due to the passing of time?
