وَإِمَّا نُرِيَنَّكَ بَعۡضَ ٱلَّذِي نَعِدُهُمۡ أَوۡ نَتَوَفَّيَنَّكَ فَإِلَيۡنَا مَرۡجِعُهُمۡ ثُمَّ ٱللَّهُ شَهِيدٌ عَلَىٰ مَا يَفۡعَلُونَ ٤٦
And whether We show you some of what We promise them, [O Muḥammad], or We take you in death, to Us is their return; then, [either way], Allāh is a witness concerning what they are doing.
Translation: Saheeh International (English)
Each word's meaning and sound
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.
