Need the references of two hadiths (for answering shia claims)
 

I just needed to know the references of two hadiths for answering shia claims. one is where Prophet Muhammad (S) asked the sahaba (R) to ask Abu Bakr (R) to lead the prayer.
another is that Rasulullah (S) said that this ummah will be divided into three groups regarding Ali (R).

Also could anyone post links to articles which refute shia claims about Abu Bakr (R) in light of authentic hadith. JZK.

Search the forum there are quite a number of threads dedicated to shias. Also u can search for the talks of ml taha karaan about this.
