Does the statement "Ya Muhammadah!" which was the slogan of the Muslims in the Battle of Yarmouk, imply seeking aid, and what is the ruling on saying "Ya Muhammad, help!"?

The slogan "Ya Muhammadah!" or "Wa Muhammadah!" if used in a battle by Muslims, does not necessarily mean seeking aid (istighathah). Rather, it is an exclamation of lament (nudbah) and a call to raise morale, expressing sorrow for the Prophet (peace be upon him) and his religion, similar to saying "Wa Islamah!" (Oh, my Islam!). It is permissible to call out with "Ya" when there is no ambiguity, or with "Wa" for lamentation (nudbah).
