Chapter 12: Fear Prayer
Narrated Nafi ': Ibn 'Umar said something similar to Mujahid' s saying: Whenever (Muslims and non-Muslims) stand
face to face in battle, the Muslims can pray while standing. Ibn 'Umar added, "The Prophet (ﷺ) said, 'If
the number of the enemy is greater than the Muslims, they can pray while standing or riding
(individually).' "
