Sayyiduna Umar Ibnilkhattab Radiyallahu

Sayyiduna Umar ibnil-Khattab Radiyallahu ae anhu narrates that Rasullullah Sallallahu ae alaihi wasallam said: Indeed, if you put your faith completely in ALLAH, Subhanahu wa ta'ala, as it ought to be, then surely you will be provided sustenance as birds are provided for. They leave in the morning with their empty stomachs and return in the evening duly filled. (Tirmidhi)
