وَالَّذِينَ اجْتَنَبُوا الطَّاغُوتَ أَن يَعْبُدُوهَا وَأَنَابُوا إِلَى اللَّهِ لَهُمُ الْبُشْرَىٰ ۚ فَبَشِّرْ عِبَادِ ۝ الَّذِينَ يَسْتَمِعُونَ الْقَوْلَ فَيَتَّبِعُونَ أَحْسَنَهُ ۚ أُولَٰئِكَ الَّذِينَ هَدَاهُمُ اللَّهُ ۖ وَأُولَٰئِكَ هُمْ أُولُو الْأَلْبَابِ

The present world is one of trial. Here, realities do not reveal themselves in their true and final shape, which makes room for anything to be wrongly interpreted. Satan exploits this possibility and misguides people from the right path. Whenever a Truth reveals itself, Satan tries to divert people’s minds from it by misinterpreting it. He turns away the good aspect of a thing and brings to the fore whatever is unfavourable about it. This is a situation in which a man is really put to the test. Man has to prove his wisdom by distinguishing between right and wrong. He should be able to tear down the satanic veil of deception and see the reality. Those who have proved themselves to be in possession of such insight are the fortunate ones because they will find the Divine Truth; those who fail to prove this are fated to be enmeshed in the negative aspect of things, and are liable to be brought before God as worshippers of Satan.
