This short series of lectures was in commentary and elaboration of a certain Islamic poem about "migrating" to Islam and away from "false" worship, corrupting theological innovations, and the evils of the self. I was not able to pinpoint the exact name of the author for the original text ... in this case, the title alone was insufficient for finding it on Google, and I would have bothered trying to write down the lengthy name by simply hearing it, but it appears that the two audio files included in Richardson's larger audio book (Islamic Beliefs; the book being a set of discourses on many different works by Muslim writers) only actually addressed parts of the poem anyway.
Therefore, deviating from my usual approach a little, I have added this book to Goodreads with sole attribution to Moosaa Richardson. This makes enough sense anyway, as 90% of the content is his commentary. And, as always, the commentary is very enlightening on the principles of the Islamic faith. Very conservative, I dare say - perhaps even with a fundamentalist bent - and it does include a particularly off-putting, shouted rant against Christians and Jews towards the end. But I do appreciate and gravitate towards much of Richardson's expositions, and his commitment to orthodox faith is inspiring.
By and large, I have greatly enjoyed his Islamic Beliefs - this section being the final part of the 51 hour-long audiobook (found in its entirely on Spotify), which I have been listening to intermittently since 2019.
