Question:
(The one) who separated from Mu'adh... did he pray alone?
Answer:
Yes, he separated from Mu'adh and prayed alone.
Q: Is there a ruling permitting separation when there is a need?
The Shaykh: It is permissible if the imam prolongs the prayer, making it difficult for some of the ma'mum, and one has a need or is weak; because the Messenger of Allah (peace and blessings be upon him) did not rebuke him, but rather rebuked Mu'adh.
