﴿ مَتَٰعٌۭ فِى ٱلدُّنْيَا ثُمَّ إِلَيْنَا مَرْجِعُهُمْ ثُمَّ نُذِيقُهُمُ ٱلْعَذَابَ ٱلشَّدِيدَ بِمَا كَانُوا۟ يَكْفُرُونَ ﴾

“[A brief] enjoyment in this world-and thereafter unto Us they must return: and then We shall let them taste suffering severe as an outcome of their persistent denial of the truth.”

(This world's portion (will be theirs)) they will live in the life of this world a little, (then unto Us is their return) after they die. (Then We make them taste a dreadful) a severe (doom because they used to disbelieve) in Muhammad (pbuh) and in the Qur'an and also because they invented lies about Allah.
