﴿ فَإِن تَوَلَّوْا۟ فَإِنَّمَا عَلَيْكَ ٱلْبَلَٰغُ ٱلْمُبِينُ ﴾

“BUT IF they turn away [from thee, O Prophet, remember that] thy only duty is a clear delivery of the message [entrusted to thee].”

(Then, if they turn away) from faith, (thy duty (O Muhammad) is but plain conveyance (of the message)) from Allah in a language that you understand.
