فَٱصْبِرْ إِنَّ وَعْدَ ٱللَّهِ حَقٌّۭ ۚ فَإِمَّا نُرِيَنَّكَ بَعْضَ ٱلَّذِى نَعِدُهُمْ أَوْ نَتَوَفَّيَنَّكَ فَإِلَيْنَا يُرْجَعُونَ
Then have patience (O Muhammad). Lo! the promise of Allah is true. And whether we let thee see a part of that which We promise them, or (whether) We cause thee to die, still unto Us they will be brought back.
