The ma'mum preceding his imam by a slight amount
Machine translationRead the Arabic original
Question:
Honorable Shaykh, may Allah grant you success. The questioner says: If the ma'mum precedes his imam, and this precedence is very slight, does it invalidate the prayer?
Answer:
If he does it intentionally, the prayer is invalid. If he does not do it intentionally, he goes back. If he preceded his imam without realizing it, he goes back. If he realized it, he goes back and becomes behind his imam, and it does not harm him, if Allah wills.
