Jami‘ at-Tirmidhi 3392

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).’”

Shaddad bin Aws narrated that:The Prophet (ﷺ) said to him: “Should I not direct you to the chief of supplications for forgiveness? ‘O Allah, You are my Lord, there is none worthy of worship except You, You created me and I am Your slave. I am adhering to Your covenant and Your promise as much as I am able to, I seek refuge in You from the evil of what I have done. I admit to You your blessings upon me, and I admit to my sins. So forgive me, for there is none who can forgive sins except You (Allāhumma anta rabbī lā ilāha illā anta, khalaqtanī wa ana `abduka, wa ana `alā `ahdika wa wa`dika ma-staṭa`tu. A`ūdhu bika min sharri ma ṣana`tu, wa abū'u ilayka bini`matika `alayya wa a`tarifu bidhunūbī faghfirlī dhunūbī innahu lā yaghfirudh-dhunūba illā ant).’ None of you says it when he reaches the evening, and a decree comes upon him before he reaches morning, except that Paradise becomes obligatory upon him. And none says it when he reaches the morning, and a decree comes upon him before he reaches evening, except that Paradise becomes obligatory for him.”

Abdullah said:“When he reached the evening, the Prophet (ﷺ) used to say, ‘We have reached the evening, and the Dominion has reached the evening, while belonging to Allah. And all praise belongs to Allah. None has the right to be worshiped but Allah, alone, without partner. (Amsaina wa amsal-mulku lillāh, wal-ḥamdullilāh, wa lā ilāha illallāh, waḥdahu lā sharīka lahu)’ – I think he said [in it]: - ‘To Him belongs the Dominion, and to Him is the praise, and He is capable of all things. I ask You for the good that is in this night, and the good of what is after it, and I seek refuge in You from the evil of this night, and the evil of what is after it, and I seek refuge in You from laziness and helpless old age. And I seek refuge in You from the punishment of the Fire and the punishment of the grave (Lahul-mulku wa lahul-ḥamdu, wa huwa `alā kulli shai'in qadīr. Asa'luka khaira mā fī hādhihil-lailah, wa khaira mā ba`dahā, wa a`ūdhu bika min sharri hādhihil-lailati wa sharri mā ba`dahā, wa a`ūdhu bika minal-kasali wa sū'il-kibar, wa a`ūdhu bika min `adhābin-nāri wa `adhābil-qabr).’ And when he reached the morning, he (ﷺ) used to say, ‘We have reached the morning, and the Dominion has reached the morning, while belonging to Allah. And all praise belongs to Allah (Aṣbaḥnā wa aṣbaḥal-mulku lillāh, wal-ḥamdulillāh).’”
