Musnad Ahmad 1153:154

Jarir narrated to us, from Mansur, from Abu al-Duha, from Masruq, from Aisha, who said: The Messenger of Allah (peace and blessings of Allah be upon him) used to frequently say in his bowing and his prostration: "Glory be to You, O Allah, our Lord, and with Your praise. O Allah, forgive me," interpreting the Quran.
