Jami at-Tirmidhi Hadith 3391

Abu Hurairah (ra) said: The Messenger of Allah (ﷺ) used to teach his Companions, saying: “When one of you reached the morning, then let him say: ‘O Allah, by You we enter the morning, and by You we enter the evening, and be You we live, and by You we died, and to You is the Return (Allāhumma bika aṣbaḥnā wa bika amsainā wa bika naḥyā wa bika namūtu wa ilaikal-maṣīr). And when he reaches the evening let him say: ‘O Allah, by You we enter the evening, and by You we enter the morning, and by You we live, and by You we die, and to You is the Resurrection (Allāhumma bika amsainā wa bika aṣbaḥnā wa bika naḥyā wa bika namūtu wa ilaikan-nushūr).’”
