﴿ وَإِن يَكَادُ ٱلَّذِينَ كَفَرُوا۟ لَيُزْلِقُونَكَ بِأَبْصَٰرِهِمْ لَمَّا سَمِعُوا۟ ٱلذِّكْرَ وَيَقُولُونَ إِنَّهُۥ لَمَجْنُونٌۭ ﴾

“Hence, [be patient,] even though they who are bent on denying the truth would all but kill thee with their eyes whenever they hear this reminder, and [though] they say, "[As for Muhammad,] behold, most surely he is a madman!"”

The relationship between the missionary and his addressees is a very delicate one. The missionary has to make himself pleasant-mannered unilaterally. The addressee may talk unreasonably, he may hold the missionary in contempt, and may make false allegations against him. In short, he may do anything of a discourageing nature, but the missionary must at all times abstain from negative reaction. His success is dependent upon two things—tolerance of excesses on the part of the addressee and having no expectation of material gain from him.
