Hadith 934
Sayyiduna Rafi‘ bin Khadij (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings be upon him) would not rise from his gathering without reciting this supplication: “«سُبْحَانَكَ اللّٰهُمَّ وَبِحَمْدِكَ أَسْتَغْفِرُكَ وَأَتُوبُ إِلَيْكَ»”, then he would say: “This is an expiation for the gathering.”
