In the Quran, the topics of the unity of God and the Hereafter have been described again and again in a number of different ways. If a man is serious, these discourses are enough to arouse his interest. But one who is unheeding is not influenced by any argument. Undertaking the great jihad by means of the Quran means a peaceful struggle to spread the word of God. That is to say, peaceful struggle is the real jihad—nay, the greatest jihad. Even if opponents try to divert the attention of the believers from the realm of peaceful efforts, it should then be the endeavour of the believers to concentrate upon the field of preaching based on the teachings of the Quran. However, if, due to the distraction caused by opponents, the field of action appears to be changing at any time, then all possible efforts should be made to bring it back to the field of peaceful activity aimed at conveying the message of the Quran.
