﴿ وَإِمَّا نُرِيَنَّكَ بَعْضَ ٱلَّذِى نَعِدُهُمْ أَوْ نَتَوَفَّيَنَّكَ فَإِلَيْنَا مَرْجِعُهُمْ ثُمَّ ٱللَّهُ شَهِيدٌ عَلَىٰ مَا يَفْعَلُونَ ﴾

“And whether We show thee [in this world something of what We hold in store for those [deniers of the truth], or whether We cause thee to die [before that retribution takes place - know that, in the end], it is unto Us that they must return; and God is witness to all that they do.”
