From the Signposts of Tawheed

Indeed Tawheed is the beginning of the religion and its end; its inner core and outer shell; and it is the beginning and end of the call of the messengers. It is the meaning of the statement: None has the right to be worshiped except Allaah. Due to it the creation was created, the messengers were sent, and the books were revealed. By way of it the people are divided into believers and disbelievers; blessed people of paradise and wretched people of the fire. It is the first obligation upon the responsible person and it is the reality of the religion of Al-Islaam besides which Allaah will not accept any other religion. Therefore, its affair is of the utmost importance and it is very great. Each of us is in need of being reminded of it and enlightened regarding it.
