Brother, I am not doubting this Hadith at all.....simply asking for verification that it is authentic, as I do not have Muslim Shareef to hand. More importantly, I wanted to know if it is referring to the Final Sermon of our Beloved Rasul salallahu alaihi wasallam in which the reference is to Quran and Sunnah, not Progeny as stated in this particular Hadith. If it is referring to a separate issue/context, then any information is welcome. When I mentioned this to an acquaintance, they simply said it could be from a Shia source without further clarification, hence I thought I'd pose the question here. I apologise if I did not make myself clear. Hope someone can clarify it. Jzk.
