At-Tawbah · 9:127

127. Whenever Allah reveals a sūrah to the Messenger (peace be upon him), mentioning the states of the hypocrites, the hypocrites would look at one another, saying ‘Does anyone see you?’ If no one is looking at them, they leave the gathering. Allah turned their hearts away from guidance and goodness, and leaves them, because they are a people who do not understand.
