Al-Baqarah 2:14

Wa-itha laqoo allatheena amanooqaloo amanna wa-itha khalaw ilashayateenihim qaloo inna maAAakum innamanahnu mustahzi-oon

And when they meet those who believe, they say, "We believe"; but when they are alone with their evil ones, they say, "Indeed, we are with you; we were only mockers."

When they meet those who believe, they say, “We have entered Faith;” but when they are alone with their satans, they say, “Indeed, we are with you; we were only mocking.”
