Narrated `Aisha (May Allah be pleased with her) :
The Prophet (ﷺ) used to say in his bowing and prostrations
سُبْحَانَكَ اللَّهُمَّ رَبَّنَا وَبِحَمْدِكَ اللَّهُمَّ اغْفِرْ لِي
“Subhanaka l-lahumma Rabbana wa bihamdika; Allahumma ghfir li , Glory be to Thee, O Allah, out Lord.” And “Praise be to Thee, O Allah, forgive me,”
Sahih al-Bukhari Book 10, Hadith 189
