Sayyiduna Sahl bin Abi Hathmah (may Allah be pleased with him) narrates about the prayer of fear: One group will stand in front of the Imam and the other group will stand behind the Imam. The Imam will lead this group (the one behind him) in one rak'ah and two prostrations. Then this group will remain seated in their place until those people (the other group) perform one bowing and two prostrations (of the second rak'ah). Then those people will go to the place of their companions and their companions will come to their place. The Imam will lead them in one bowing and two prostrations. The Imam will remain seated in his place until those people also perform one bowing and two prostrations, then the Imam will say the salam (to end the prayer).

This same narration has been transmitted by Imam Ibn Khuzaymah with his chain from Sayyiduna Sahl bin Abi Hathmah (may Allah be pleased with him) from the Prophet Muhammad (peace and blessings be upon him) in a similar manner.
