I wish to know how to rely on Allah during trade.

Reliance on Allah for sustenance is a sign of faith, the system of faith, and the companion of monotheism. It leads to the eradication of poverty and peace of mind. To combine reliance on Allah with trade, the servant should believe that Allah has apportioned and destined provisions, sever their dependence on anyone other than Allah, and keep their heart reliant on Allah while exerting effort and striving. They should also have a good opinion of Allah and resort to Him through supplication.
