Dua said at a sitting or gathering etc.

Ibn 'Umar (radhi-yAllaahu 'anhumaa) said: It would be counted that at any one sitting, the Messenger of Allaah (sal-Allaahu 'alayhe wa sallam) before getting up would say one hundred times:

رَبِّ اغْفِرْ لِيْ وَتُبْ عَلَىَّ إِنَّكَ أَنْتَ التَّوَّابُ الْغَفُوْرُ

My Lord, forgive me and accept my repentance, You are the Ever-Relenting, the All-Forgiving.

Rabbighfir lee wa tub 'alayya 'innaka 'Antat-Tawwaabul-Ghafoor.
