What is the supplication for concluding a gathering?

The supplication for concluding a gathering is: "Glorified art You, O Allah, and with Your praise; I bear witness that there is no god but You; I seek Your forgiveness and repent to You." This is based on what was narrated by Imam Ahmad and At-Tirmidhi from Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace be upon him) said: "Whoever sits in a gathering where there is much idle talk, and says before rising from that gathering: 'Glorified art You, O Allah, and with Your praise; I bear witness that there is no god but You; I seek Your forgiveness and repent to You,' he will be forgiven for what occurred in that gathering."
