we need to unite , but there is no unity under the cloak of shirk and kufr, we must unite under the banner of Islam, on the Quran and True Sunnah of our Prophet Muhammad (s)...We must have the same common belief in Allah.
We must believe in the shahadah:
[ʾaÅ¡hadu ʾan] lÄ ilÄha illÄ-llÄh, wa [ʾaÅ¡hadu ʾanna] muḥammadan rasÅ«lu-llÄh
[ I testify that ] there is none worthy of worship except God, and [I testify that] Muhammad is the messenger of God.
