Riyad us Saliheen: Hadith 1452

The Prophet (ﷺ) used to say in the morning: "Allahumma bika asbahna, wa bika amsaina, wa bika nahya, wa bika namutu, wa ilaikan-nushur (O Allah! With Your Power we have come to the morning, with Your Power we come to the evening, with Your Power we live, and we die, and to You will we return)." In the evening he would say: "Allahumma bika amsaina, wa bika nahya, wa bika namutu, wa ilaikan-nushur (O Allah! With Your Power, we have come to the evening, by You do we live, by You do we die, and to You is the return)."

[At-Tirmidhi and Abu Dawud].
