The Prescribed Supplication in Prostration

Question:
May Allah reward you with good and do you well. A listener sent a message asking and saying: In the prayer, in the prostration, I say after “Subhanaka Allahumma wa bihamdika, Allahumma ighfir li” (Glory is to You, O Allah, and praise is to You, O Allah, forgive me), “Ya Muqallib al-qulub, thabbit qalbi 'ala dinik” (O Turner of hearts, make my heart firm upon Your religion). After that, I say, “My Lord, forgive me and my parents, and have mercy on them as they raised me when I was small. O Allah, grant me the pleasure of gazing at Your noble Face, without any harmful adversity or misleading trial. O Allah, rectify my wife, my children, and all my descendants. O Allah, make the noble Qur'an the spring of our hearts. O Lord, increase us in knowledge, and grant us its understanding and its memorization.” May Allah reward you with good.
