Fear Prayer

"Narrated Shu'aib:\n\nI asked Az-Zuhri, \"Did the Prophet (ﷺ) ever offer the Fear Prayer?\" Az-Zuhri said, \"I was told by Salim\n\nthat `Abdullah bin `Umar I had said, 'I took part in a holy battle with Allah's Messenger (ﷺ) I in Najd. We\n\nfaced the enemy and arranged ourselves in rows. Then Allah's Messenger (ﷺ) (p.b.u.h) stood up to lead the\n\nprayer and one party stood to pray with him while the other faced the enemy. Allah's Messenger (ﷺ) (p.b.u.h)\n\nand the former party bowed and performed two prostrations. Then that party left and took the place of\n\nthose who had not prayed. Allah's Messenger (ﷺ) prayed one rak`a (with the latter) and performed two\n\nprostrations and finished his prayer with Taslim. Then everyone of them bowed once and performed\n\ntwo prostrations individually.' \"\n\nNarrated Nafi`:\n\nIbn `Umar said something similar to Mujahid's saying: Whenever (Muslims and non-Muslims) stand\n\nface to face in battle, the Muslims can pray while standing. Ibn `Umar added, \"The Prophet (ﷺ) said, 'If\n\nthe number of the enemy is greater than the Muslims, they can pray while standing or riding\n\n(individually).' \"\n\nNarrated Ibn `Abbas:\n\nOnce the Prophet (p.b.u.h) led the fear prayer and the people stood behind him. He said Takbir\n\n(Allahu-Akbar) and the people said the same. He bowed and some of them bowed. Then he prostrated\n\nand they also prostrated. Then he stood for the second rak`a and those who had prayed the first rak`a\n\nleft and guarded their brothers. The second party joined him and performed bowing and prostration\n\nwith him. All the people were in prayer but they were guarding one another during the prayer."
