أَسْمِعْ بِهِمْ وَأَبْصِرْ يَوْمَ يَأْتُونَنَا ۖ لَٰكِنِ ٱلظَّٰلِمُونَ ٱلْيَوْمَ فِى ضَلَٰلٍ مُّبِينٍ

The Messiah and all the other prophets called upon the people to tread the same straight path, namely, that of taking God as their Lord and worshipping Him alone. But, it has always happened that, by willful misinterpretations and false explanations, there have been deviations from the straight path. Different people have emphasized different points of the doctrine. These divergent views have led to such major differences that a single religion has been divided into several religions. The Truth is manifested in its entirety in this world too. But because here man has been given freedom of choice so that he may be put to the test, as the very purpose of his existence is trial, he may accept the Truth or he may not. Due to this temporary freedom, he falls a prey to misunderstanding and starts behaving arrogantly. He is shown the right path of God but, in spite of arguments in its favour, he does not accept it. Today his eyes and ears appear to be altogether devoid of the powers of seeing and hearing, but, in the Hereafter, when his freedom is snatched away from him, these very same eyes and very same ears of his will become so powerful that he will have no choice but to see and hear the Truth.
