رَضُواْ بِأَن يَكُونُواْ مَعَ الْخَوَالِفِ

They are content to be with those who sit behind.
 
وَطُبِعَ عَلَى قُلُوبِهِمْ

Their hearts are sealed up,

because of their staying away from <b>Jihad</b> and from accompanying the Messenger in Allah's cause,
 
فَهُمْ لَا يَفْقَهُونَ
 
 

so they understand not.

they neither understand what benefits them so that they perform it nor what hurts them so that they avoid it
