We are most knowing of what they say, and you are not (50:45)

Almuntakhab Fi Tafsir Alquran Alkarim

We know best what they -the infidels- say, and you O Muhammad never forced them to follow you or your admonition nor did you erect among them tyrannies. Therefore, keep reminding people of their duty to Allah, their Creator, and proclaim the Quran to those who regard Allahs warning with reverence and awe, tinged with latent fear

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(50:45) (O Prophet), We are well aware of what they say; *55 and you are not required to force things on them. So exhort with the Qur'an all those who fear My warning. *56

*55) In this sentence there is consolation for the Holy Prophet as well as a threat for the disbelievers. Addressing the Holy Prophet it has been said: "Do not care at aII about what these foolish people utter about you: We are hearing everything and it is for Us to deal with it. " The disbelievers are being warned to the effect: "The taunting remarks that you are passing against Our Prophet, will cost you dearly. We Our self are hearing everything that you utter and you will have to suffer for its consequences."
*56) This does not mean that the Holy Prophet wanted to compel the people into believing and AIlah stopped him from this, but, in fact, although the Holy Prophet has Been addressed the disbelievers are being warned, as if to say, 'Our Prophet has not been sent as a dictator over you. He is not there to compel you to become believers even if you did not wish to believe. His only responsibility is that he should recite the Qur'an and make the truth plain to the one who would take the warning. Now, if you do not accept his invitation, We Our self will deal with you, not he."

اے نبیؐ، جو باتیں یہ لوگ بنا رہے ہیں انہیں ہم خوب جانتے ہیں، اور تمہارا کام ان سے جبراً بات منوانا نہیں ہے بس تم اِس قرآن کے ذریعہ سے ہر اُس شخص کو نصیحت کر دو جو میری تنبیہ سے ڈرے
