Musannaf Ibn Abi Shaybah 8498 — The fear prayer: how many rakahs it is

Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) said: The Prophet (peace and blessings be upon him) led the people in the fear prayer in this way: one row stood in front of him and one row behind him. He led the group behind him in one rak'ah; then the group facing the enemy came and stood in the place of these people, and he led them in one rak'ah and gave the salam. In this way the Prophet (peace and blessings be upon him) had two rak'ahs, and each of the two groups had one rak'ah.
