Surah At-Tawbah, ayah 87

9:87

رَضُواْ بِأَن يَكُونُواْ مَعَ ٱلۡخَوَالِفِ وَطُبِعَ عَلَىٰ قُلُوبِهِمۡ فَهُمۡ لَا يَفۡقَهُونَ ٨٧

Radū bi an yakūnū ma'al-khawālifi watubi'a 'alā qulūbihim fahum lā yafqahūn

They were satisfied to be with those who stay behind, and their hearts were sealed over, so they do not understand.
