﴿ وَلَا تَسُبُّوا۟ ٱلَّذِينَ يَدْعُونَ مِن دُونِ ٱللَّهِ فَيَسُبُّوا۟ ٱللَّهَ عَدْوًۢا بِغَيْرِ عِلْمٍۢ ۗ كَذَٰلِكَ زَيَّنَّا لِكُلِّ أُمَّةٍ عَمَلَهُمْ ثُمَّ إِلَىٰ رَبِّهِم مَّرْجِعُهُمْ فَيُنَبِّئُهُم بِمَا كَانُوا۟ يَعْمَلُونَ ﴾

“But do not revile those [beings] whom they invoke instead of God, lest they revile God out of spite, and in ignorance: for, goodly indeed have We made their own doings appear unto every community In time, [however,] unto their Sustainer they must return: and then He will make them [truly] understand all that they were doing.”

Those who reject the divine message invent different excuses to justify their doing so. In these circumstances, it may occur to the preacher that he should change the way he conveys his message, so that it becomes acceptable to the addressees. But this would not be proper. He should adhere to the style which has been directly taught to him by God, because the real purpose of his activity is to link man with God and not to win people over and draw them into his sphere by hook or by crook. On the other hand, neither is it proper to respond to the addressee’s obduracy with abusive outbursts. The individual develops a bias in favour of the particular traditions to which he is born, or the kind of thinking with which he has become familiar. According to this, he develops a particular frame of mind which affects all his thinking process. This frame of mind presents the greatest impediment to the acceptance of Truth. Unless it can be altered, that door of his mind, through which the voice of Truth might enter, will never open.
