This audio by Abu Hafsah Kashiff Khan (hafidhahullah Ta'ala) was found on the YouTube Channel of Umm Uthmaan al-Majariyyah (may Allah have mercy upon her).
Another excellent quality audio that needed very little editing. It deals with the subject matter of bid'ah (innovative actions not legislated in the religion of Islam). In it he gives a comprehensive definition, rulings & categories based upon a lecture delivered by Shaykh Saalih al-Fawzaan (hafifhahullah Ta'ala).
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]
