question #1 Sahih al-Bukhari 943, Book 12, Hadith 2 : How should Muslims perform their prayers during a battle when facing a larger enemy force?

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).’ ”
