Tafsir of Fussilat 41:43

ما يقال لك إﻻ ما قد قيل للرسل من قبلك

Nothing is said to you except what was said to the Messengers before you. Qatadah, As-Suddi and others said, "Nothing is said to you by way of rejection and disbelief, that was not said to the Messengers who came before you. Just as you have been rejected, they were also rejected. Just as they bore their people's insults with patience, so too you must bear your people's insults with patience.''

إن ربك لذو مغفرة

Verily, your Lord is the Possessor of forgiveness, means, for those who turn to Him in repentance.

وذو عقاب أليم

and (also) the Possessor of painful punishment. means, for those who persist in disbelief, transgression and stubborn opposition
