Allah making someone a means for obtaining provision or averting harm for another
Is there any human who can provide sustenance to other creatures or protect them from harm?
Allah is the All-Provider, Owner of Power, the Most Strong. It is He Who answers those in despair when they call upon Him, removes evil, and repels harm. As for humans, Allah may make them only a means of providing sustenance for others and repelling harm from them. However, they can neither benefit nor harm themselves or others.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
