Quran 40:77 Ghafir, ayah 77 of 85

فَٱصْبِرْ إِنَّ وَعْدَ ٱللَّهِ حَقٌّ ۚ فَإِمَّا نُرِيَنَّكَ بَعْضَ ٱلَّذِى نَعِدُهُمْ أَوْ نَتَوَفَّيَنَّكَ فَإِلَيْنَا يُرْجَعُونَ ۝٧٧

40:77 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.
