﴿ مِّن وَرَآئِهِۦ جَهَنَّمُ وَيُسْقَىٰ مِن مَّآءٍۢ صَدِيدٍۢ ﴾

“with hell awaiting him; and he shall be made to drink of the water of most bitter distress,”

(Hell is before him) Hell is before this arrogant person when he dies, (and he is made to drink a festering water) and he is made to drink what comes of his skin of puss and blood.
