salaam alaikum,
i watched a video on utube by dr zakir naik about creating sects and
following sahih hadiths etc and how bad creating groups is in islam.
heres the link
http://www.youtube.com/watch?v=-exUaeDB858&feature=relatedor just type "unity of the ummah by dr zakir naik" in u tube
please watch the whole lecture as it is in sections
alhamdulillah he has given ayahs from the quran and explains clearly so it should easily be understood why we shouldnt consider ourselves as "sunni muslims" but muslims who follow the authentic sunna and quran
