Wa 'alaykum u salam wa rahmatullaahi wa baarakatu, ya akhee,
In Shaikh Ibn Baaz's highly beneficial book (second edition, translated) "Explanation of Important Lessons (for every Muslim)," the last (18th) chapter is a tremendously detailed 36-page chapter on this very subject. May Allaah have mercy on Shaikh Ibn Baaz.
