How did the Messenger of Allah, peace and blessings be upon him, order Hilal ibn Umayyah to participate in jihad in the Battle of Tabuk when he was old and unable to care for himself, knowing that jihad is not obligatory for the elderly?

We summarize what was mentioned in the following points:

- The fact that a man is unable to serve himself at home does not indicate his inability to engage in jihad.

- Allah called upon the youth and the elderly for jihad; He Almighty said: (Go forth, lightly and heavily).

- The statement of Hilal ibn Umayyah’s wife: “He has no servant” and “He has no energy for anything, by Allah, he kept crying” indicates that his severe grief and the lack of a servant were what compelled her to serve him.

- Sa’id ibn Zayd mentioned that Hilal ibn Umayyah prostrated after the good news, and did not raise his head until he thought he would die from the effort and crying.
