The system of dajjal (antichrist) should be pitch-black dark whereas prevalence of Islam should be brilliantly shining. But after the prevalence there is the afternoon time of the sun of Islam and the sun is gradually setting. Now, we come to the noon of Islam, the Sun is shining. Then, we will not be able to see this light after Hijri 1543. The light will fade of gradually and finally it will be pitch-black dark. - Harun Yahya
