Surah Al-Munafiqun — Ayah 2 (63:2)
ٱتَّخَذُوٓاْ أَيۡمَٰنَهُمۡ جُنَّةٗ فَصَدُّواْ عَن سَبِيلِ ٱللَّهِۚ إِنَّهُمۡ سَآءَ مَا كَانُواْ يَعۡمَلُونَ ٢
English translation (Saheeh International)
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.
Brief commentary
They have made the oaths that they swear on their claim of faith a cover and protection for them from being killed or imprisoned. They turned people away from faith by the doubts and rumours that they spread. Evil is the hypocrisy and false oaths that they perpetrate.
