﴿ مَن يَأْتِيهِ عَذَابٌۭ يُخْزِيهِ وَيَحِلُّ عَلَيْهِ عَذَابٌۭ مُّقِيمٌ ﴾

“who it is that shall be visited [in this world] by suffering which will cover him with ignominy, and upon whom long-lasting suffering shall alight [in the life to come]!””

to whom man introduces the relative clause that is the direct object of the action of ‘knowing’ will come a chastisement that will disgrace him and on whom there will descend a lasting chastisement’ an everlasting one namely the chastisement of the Fire. Indeed God then disgraced them at Badr.
