ٱلْأَخِلَّآءُ يَوْمَئِذٍ بَعْضُهُمْ لِبَعْضٍ عَدُوٌّ إِلَّا ٱلْمُتَّقِينَ

Man is not free. At all events, he has to humbly accept reality. If he does not defer to the reasoning of the preacher of Truth, he shall have to submit to godly power. But godly power comes into play only at the time of the Final Judgement. Therefore, doing obeisance only at that time and not before will be of no avail to anybody. In this world, when a man adopts any course which is opposed to the Truth, he finds many friends to support him. Man becomes bolder and bolder on the strength of such friendship. But all these friends will abandon him on the Day of Judgement. On that Day, only that friendship will last which has been established on the basis of the fear of God. A life which is dedicated to the Truth is fraught with dangers. But in the Hereafter, it will be permanently relieved of every type of fear or trouble. Only those who firmly believe in this godly assurance will remain steadfastly on the path of Truth in this world. In the life Hereafter, God will bestow on them much more than they lost in this world for His sake.
