﴿ وَإِن يُكَذِّبُوكَ فَقَدْ كُذِّبَتْ رُسُلٌۭ مِّن قَبْلِكَ ۚ وَإِلَى ٱللَّهِ تُرْجَعُ ٱلْأُمُورُ ﴾

“But if they [whose minds are perverted] give thee the lie, [O Prophet, remember that] even so, before thy time, have [other] apostles been given the lie: for [the unbelievers always refuse to admit that] all things go back to God [as their source].”

(And if they) the Quraysh (deny thee, (O Muhammad), messengers (of Allah) were denied before thee) their folks denied them just as your people are denying you. (Unto Allah all things are brought back) the end results of all things are brought back to Allah in the Hereafter.
