Additions to the Kalma Tayyaba

Re: Additions to the Kalma Tayyaba

‘LA ILAHA ILLALLAH MUHAMMAD- AR RASOOL-ALLAH is not a minimum requirement untill or unless you wont say " i testify that there is no God but ALLAH and i testify tht PROPHET MUHAMMAD SAWW is the last PROPHET of ALLAH", just believe in LA ILAHA ILLALLAH MUHAMMAD- AR RASOOL-ALLAH doesnt full fill the minimum conditions of “testify” which is obligatory to be a muslim..
as far as the adding word is concern at the end of LA ILAHA ILLALLAH MUHAMMAD- AR RASOOL-ALLAH, as i mention these are just 2 diffent ayats of QURAN and our beloved PROPHET never said that only believes in these ayat are enough to be a muslim.. if said then prove it from authentic HADIS.
