Your welcome brother Sami2000..
The truth must be told.. Sunni people are those who followed the message of Prophet Mohammad since the beginning, And followed his teachings step by step.
Allah (SWT) says: Say (O Muhammad SAW to mankind): "If you (really) love Allâh then follow me (i.e. accept Islâmic Monotheism, follow the Qur'ân and the Sunnah), Allâh will love you and forgive you your sins. And Allâh is Oft-Forgiving, Most Merciful." (31) Say (O Muhammad SAW): "Obey Allâh and the Messenger (Muhammad SAW)." But if they turn away, then Allâh does not like the disbelievers[] (32)[Surat Al-E-Imran 3]
(But if they turn away, then Allâh does not like the disbelievers)
So whoever choses not to follow the teachings of the prophet, Is considered a disbeliever.
