Surah Al-Munafiqun, ayah 2

63:2

ٱتَّخَذُوٓاْ أَيۡمَٰنَهُمۡ جُنَّةٗ فَصَدُّواْ عَن سَبِيلِ ٱللَّهِۚ إِنَّهُمۡ سَآءَ مَا كَانُواْ يَعۡمَلُونَ ٢

Ittakhadhū aymānahum junnatan fasaddū 'an sabīlillāhi innahum sā'a mā kānū ya'malūn

They have taken their oaths as a cover, so they averted [people] from the way of Allāh. Indeed, it was evil that they were doing.
