Sayyiduna Abdullah (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) led us in the prayer of fear. The people formed two rows: one row stood following the Prophet Muhammad (peace and blessings be upon him), and the other stood facing the enemy. The Prophet Muhammad (peace and blessings be upon him) led these people in one rak'ah, then the other group came and took their place, and these people went to face the enemy. The Prophet Muhammad (peace and blessings be upon him) led them in one rak'ah and then said the salam. Then these people stood up and completed their prayer and said the salam. Then these people went and stood facing the enemy in place of the first group, and the first group returned to their place, performed one rak'ah themselves, and said the salam.
