Is it correct aqeedah to believe Allah grants us health and rizq first given to Muhammad (saw) then given to us through him saw

In the Name of Allah, the Most Gracious, the Most Merciful.

As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.

You enquire if it is correct to have the belief, that Allah Subhanahu Wa Ta’ala first grants health and sustenance to the Prophet Salallahu Alaihi Wa Sallam, then through him to the people.

The aqeedeh in reference is incorrect and has no basis in Islam.

Allah Subhanahu Wa Ta’ala gives sustenance and health directly, without the medium of the Prophet Salallahu Alaihi Wa Sallam.
