Mercy to the Worlds

The Shaykh :"Mercy to the Worlds" and the evidence for this is His saying, the Exalted: and this mercy is the object for the sake of which it was sent, its operative cause being His saying meaning that Allah sent him to show mercy to the worlds through him, and this is the reality, for the Messenger (peace and blessings be upon him) was sent, and a people from among creation followed him, so Allah showed them mercy through him.
