Here is a lecture by Abu Idrees Muhammad (hafidhahulllah Ta'ala), that I found on YouTube. It is a reminder that was not only directed at Muslims, but also to a non-Muslim audience.
It is a lecture that is over 2 hours long. It was possibly delivered as far back as in late-2012, if not earlier!
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]
