Al-Munafiqun 63:2

Ittakhathoo aymanahum junnatanfasaddoo AAan sabeeli Allahi innahum saa makanoo yaAAmaloon

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.

They have made their oaths a shield, and thus they have prevented (others) from the way of Allah. Surely evil is what they have been doing.
