and regarding their small numbers, the enemy's hiding places, and their guile. Thus, it is appropriate that their affairs be referred to his judgment, because it is more cautious for the Muslims; unless it is impossible to seek his permission due to the enemy surprising them, in which case his permission is not required because the interest is determined to lie in fighting them and going out to them, because leaving them [to their own devices] would result in certain corruption. For this reason, when the disbelievers raided the milch-camels of the Prophet (may Allah bless him and grant him peace), and Salamah ibn al-Akwa' happened upon them while he was leaving Medina, he pursued them and fought them without permission. The Prophet (may Allah bless him and grant him peace) praised him and said: "The best of our footmen (6) is Salamah ibn al-Akwa'." And he gave him the share of both a horseman and a footman (7).

He said: "No (8). He only intended (9) it for him specifically; therefore, he shall not accompany him until he gives him permission."

In my view, providing aid is superior to congregational prayer, and for the one pursuing or being pursued in this situation, praying on the back of his mount while moving is superior, if Allah, the Exalted, wills. And if he hears the call to mobilize and the prayer has already commenced, he should pray, make it brief, complete the bowing and prostration, and recite short chapters." And there was someone who mobilized from the companions of the Messenger of Allah (may Allah bless him and grant him peace) while he was in a state of major ritual impurity (junub)—meaning the one washed by the angels, Hanzalah ibn al-Rahib (11). He said: "And he does not break off the prayer when he is..."
