Surat An-Nahl (125-126)

{ادْعُ إِلِى سَبِيلِ رَبِّكَ بِالْحِكْمَةِ وَالْمَوْعِظَةِ الْحَسَنَةِ وَجَادِلْهُم بِالَّتِي هِيَ أَحْسَنُ إِنَّ رَبَّكَ هُوَ أَعْلَمُ بِمَن ضَلَّ عَن سَبِيلِهِ وَهُوَ أَعْلَمُ بِالْمُهْتَدِينَ} (النحل: 125)

125- Call to Islam with good words, convincing argument, and good style kindly and with addressing the conditions, environment, and specialties of people. Argue with your opponents with a nice style, good manners, forbearance, and mercy which is mixed by advice except those who show stubbornness and aggression.

Allah knows those who turn away from Islam and choose the way of stubbornness and error. He is most knowledgeable of those who open their hearts to the truth and choose the way of guidance and faith, you only have to report and explain the truth, and it is not your duty to guide them.

{وَإِنْ عَاقَبْتُمْ فَعَاقِبُواْ بِمِثْلِ مَا عُوقِبْتُم بِهِ وَلَئِن صَبَرْتُمْ لَهُوَ خَيْرٌ لِّلصَّابِرينَ} (النحل: 126)

126- When you want to punish someone, punish them in the same manner you were punished, so do with them as they did to you without extra punishment. However, if you observe patience and pardon, it will be better for you, and patience has a great reward. "And verily, whosoever shows patience and forgives that would truly be from the things recommended by Allah." [Surat Ash-Shura: 43]. "Only those who are patient shall receive their rewards in full, without reckoning." [Surat Az-Zumar: 10].
