Sahih Ibn Khuzaymah

Hazrat Tha’labah bin Zahdam (may Allah have mercy on him) narrates that we were with Sayyiduna Sa’eed bin ‘Aas (may Allah be pleased with him) in Tabaristan, so he asked, “Who among you has performed the prayer of fear (Salat al-Khawf) with the Messenger of Allah (peace and blessings be upon him)?” Sayyiduna Hudhaifah (may Allah be pleased with him) replied, “I have performed it.” Sayyiduna Hudhaifah (may Allah be pleased with him) stood up (to lead the prayer) and the people formed two rows behind him. One row stood behind him and the other row lined up facing the enemy. So those who were standing behind him, Sayyiduna Hudhaifah led them in one rak’ah, then these people went and took the place of those facing the enemy, and those people came and he led them in one rak’ah as well. And he did not complete (the second rak’ah). In the narration of Abu al-Sha’tha, these words are not present that he did not complete (the second rak’ah).

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) led the (fear) prayer at the place of Dhi Qarad. In the narration of Abu Musa, it is mentioned that it was like the prayer of Sayyiduna Hudhaifah (may Allah be pleased with him), and Bundar narrated a narration similar to the hadith of Sayyiduna Hudhaifah (may Allah be pleased with him), and at the end of it, he narrated these words: and he did not complete (the second rak'ah).

Qasim bin Hassan (may Allah have mercy on him) narrated from Sayyiduna Zaid bin Thabit (may Allah be pleased with him), from the Prophet (peace and blessings of Allah be upon him), a narration similar to the prayer of Sayyiduna Hudhaifah (may Allah be pleased with him).

Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates that Allah Almighty has made obligatory, through the tongue of your Prophet (peace be upon him), four rak‘ahs in residence, two rak‘ahs in travel, and one rak‘ah in a state of fear.
