Surah Al-Munafiqun, Verse 2

ٱتَّخَذُوٓاْ أَيۡمَٰنَهُمۡ جُنَّةٗ فَصَدُّواْ عَن سَبِيلِ ٱللَّهِۚ إِنَّهُمۡ سَآءَ مَا كَانُواْ يَعۡمَلُونَ٢

ittakhadhū aymānahum junnatan faṣaddū ʿan sabīli l-lahi innahum sāa mā kānū yaʿmalūna

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.
