The ruling on separating from the imam if he prolongs the prayer due to a pressing need
Machine translationRead the Arabic original
Question:
He says: If the imam prolongs the prayer, and there is a pressing need, should I separate and pray alone, then go attend to my need, or is this not permissible?
Answer:
If your need is such that you fear it will be lost if you do not attend to it, and nothing will be ruined for you or your wealth will be lost, or a fire will be lit and something stolen, then if the imam prolongs the prayer, you should separate, complete your prayer, say the closing salam, and go, just as the man who prayed behind Mu'adh (may Allah be pleased with him) did when Mu'adh prolonged the prayer and he feared that his camels would be lost. He left him, completed his prayer, and departed. This reached the Prophet (peace and blessings be upon him), and he did not disapprove of it; rather, he disapproved of Mu'adh for prolonging the prayer.
