In the name of Allah, Most Gracious, Most Merciful.
125. Invite to the Way of your Lord (i.e. Islâm) with wisdom and fair preaching, and argue with them in a way that is better. Truly, your Lord knows best who has gone astray from His Path, and He is the Best Aware of those who are guided.
126. And if you punish (your enemy), then punish them with the like of that with which you were afflicted. But if you endure patiently, verily, it is better for As-Sâbirin (the patient ones, etc.).
127. And endure you patiently, your patience is not but from Allâh. And grieve not over them, and be not distressed because of what they plot.
128. Truly, Allâh is with those who fear Him (keep their duty unto Him), and those who are Muhsinûn (good-doers).
