Here is a lecture that was delivered on the 31st of January 1992 by the Noble Shaykh Badee Uddin Shah (may Allah have mercy upon him), dealing with this issue. He comprehensively covers this topic in his unique style of deliverance.
May Allah shower the Shaykh in His all-encompassing mercy and forgive him for his shortcomings, Aameen. May He enable us to benefit fully from this reminder by one of the great Ulema of this time, from the contemporaries of Shaykhs Ibn Baaz, al-Albaanee, Ibn al-'Uthaymeen, (may and others (may Allah have mercy upon them all, Aameen).
What I have done is slow the lecture down by about 10% of its actual speed to make it a little easier for the listeners.
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]
