Hadith: In the morning, the Messenger of Allah (may Allah's peace and blessings be upon him) used to say: "O Allah, by Your leave we have reached the morning, and by Your leave we have reached the evening; by Your leave we live and by Your leave we die; and our resurrection will be to You." On the evening, he used to say the same supplication except that he would say: "and our return will be to You

عن أبي هريرة رضي الله عنه قال: كان رسول الله صلى الله عليه وسلم إذا أصبح يقول: «اللهم بك أصبحنا، وبك أمسينا، وبك نحيا، وبك نموت، وإليك النُّشُورُ» وإذا أمسى قال: «اللهم بك أمسينا، وبك نحيا، وبك نموت. وإليك المصير».
[حسن] - [رواه أبو داود والترمذي وابن ماجه]

Abu Hurayrah (may Allah be pleased with him) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) used to say on the morning: "O Allah, by Your leave we have reached the morning, and by Your leave we have reached the evening; by Your leave we live and by Your leave we die; and our resurrection will be to You." In the evening, he used to say: O Allah, by Your leave we have reached the evening; by Your leave we live and by Your leave we die; and our resurrection will be to You."

Explanation

A Muslim should seek the aid of Allah, the Almighty, and His omnipotence and power at both the beginning and end of one's day. He acknowledges that Allah, the Almighty, brought us into existence by His omnipotence; He also created the morning, the evening, life, and death. Definitely, our return and final abode after resurrection shall be to Allah, the Almighty.
