Here is a subject matter that many people fail to understand correctly. This is a comprehensive lecture that I came across on YouTube by Hasan as-Somali (hafidhahullah Ta'ala).
It has been digitally edited before being posted below, walhamdulillah.
Abu Hurairah (رضي الله عنه) narrated that the Prophet ﷺ said: "Whoever invites to guidance will be rewarded like those who follow him in the guidance are rewarded, and that will not decrease the reward of those who have followed him." [Collected by Imām Muslim]
