Our entire life is in submission to the way of Islam. One of the most brilliant aspects of the Islamic moral system is that it did not neglect single aspects of our life without setting out the laws for it. Even how we sit and how we sit among our brethren.
Here is Dua after gathering with translation, Arabic text, transliteration and explanation.
Dua After Gathering In Arabic
سُبْحـانَكَ اللّهُـمَّ وَبِحَمدِك، أَشْهَـدُ أَنْ لا إِلهَ إِلاّ أَنْتَ أَسْتَغْفِرُكَ وَأَتوبُ إِلَـيْك
Subhanaka Allahumma wabihamdika, ashhadu allailaha illa anta, astaghfiruka wa atuubu ilayka.
Dua After Gathering With Translation
The translation of Dua after leaving a gathering is Glory is to You, O Allah, and praise is to You. I bear witness that there is none worthy of worship but You. I seek Your forgiveness and repent to You.
Starting the good things with dua, it is then equally important to end it with dua. This dua is recited after a gathering or a majlis (a gathering by a group of people to talk or discuss something) that has a purpose and is expected to reap a specific benefit or goal.
For this reason, it is recommended that you should says this supplication after a sitting involving much idle talk.
Narrated AbuBarzah al-Aslami: When the Messenger of Allah (ﷺ) intended to get up from the assembly he used to say in the last.
Glory be to Thee. O Allah, and I begin with praise of Thee, I testify that there is no god but Thou; I ask Thy pardon, and return to Thee in repentance.
The man asked: Messenger of Allah! you utter the words now which you did not do in the past? He replied: (This is an) atonement for what takes place in the assembly.

Dua After Gathering Explanation
In the hadeeth of Aboo Barzah, may Allah be pleased with him, is evidence that the Prophet SAW used to practice that. He also explained that this is an expiation for sins committed in assemblies (Kaffaratul Majlis).
A man hardly sits in a gathering without indulging in a form of useless talk, amusement or waste of time. It is thus good that one says this supplication every time he gets up from an assembly:
‘Subhanaka Allahumma wabihamdika, ashhadu allailaha illa anta, astaghfiruka wa atuubu ilayka‘ so that it serves as expiation for sins committed during the assembly.
There is a lot of benefits of reciting the Duas of our beloved prophet among them is you will be forgiven for (the sins you may have intentionally or unintentionally committed) in that assembly.
