Quran

Iman

They believe in Allah and the last day, and they enjoying what is right and forbid what is wrong and hasten to good deeds. And those are among the righteours.

Belief

Indeed, those who have said, “Our Lord is Allah,” and then remained on a right course there will be no fear concerning them, nor will they grieve.

Allah’s Unity & Exclusiveness

Allah- there is no deity except Him. To Him belong the best names.
