Qaf - 50:45

نَحْنُ أَعْلَمُ بِمَا يَقُولُونَ وَمَا أَنتَ عَلَيْهِم بِجَبَّارٍ فَذَكِّرْ بِالْقُرْآنِ مَن يَخَافُ وَعِيدِ
[50:45]
We know best what they say, and you are not one to compel them; therefore remind him by means of the Quran who fears My threat.
We know best what they say; and thou art not one to overawe them by force. So admonish with the Qur'an such as fear My Warning!
We are Best Aware of what they say, and thou (O Muhammad) art in no wise a compeller over them. But warn by the Qur'an him who feareth My threat.
