And whether We show you some of what We promise them, [O (10:46)

﴿وَإِمَّا نُرِيَنَّكَ بَعْضَ الَّذِي نَعِدُهُمْ أَوْ نَتَوَفَّيَنَّكَ فَإِلَيْنَا مَرْجِعُهُمْ ثُمَّ اللَّهُ شَهِيدٌ عَلَىٰ مَا يَفْعَلُونَ﴾
[ يونس: 46]

10:46 And whether We show you some of what We promise them, [O Muhammad], or We take you in death, to Us is their return; then, [either way], Allah is a witness concerning what they are doing

Regardless of whether Allah shows the Messenger ( peace be upon him )some of the punishment He promises them before his death, or He makes him die before this, they will return to Allah on the Day of Judgement.
Moreover, Allah is a witness to what they used to do, none of it being hidden from Him, and they will be repaid for their actions.

Whether We show you (in your lifetime, O Muhammad SAW) some of what We promise them (the torment), - or We cause you to die, - still unto Us is their return, and moreover Allah is Witness over what they used to do.
