وَعَن أَبِي مَالِكٍ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ:" إِذَا أَصْبَحَ أَحَدُكُمْ فَلْيَقُلْ: أَصْبَحْنَا وَأَصْبَحَ الْمُلْكُ لِلَّهِ رَبِّ الْعَالَمِينَ اللَّهُمَّ إِنِّي أَسْأَلُكَ خَيْرَ هَذَا الْيَوْمِ فَتْحَهُ وَنَصْرَهُ وَنُورَهُ وَبِرْكَتَهُ وَهُدَاهُ وَأَعُوذُ بِكَ مِنْ شَرِّ مَا فِيهِ وَمِنْ شَرِّ مَا بَعْدَهُ ثُمَّ إِذَا أَمْسَى فَلْيَقُلْ مِثْلَ ذَلِكَ ". رَوَاهُ أَبُو دَاوُد
Translation

‘Abdallah b. Abu Aufa told that God’s messenger said in the morning, "We have reached the morning, and in the morning the dominion belongs to God; praise is due to God; majesty and might belong to God; the creation, the command, night and day and what is at rest by night and day belong to God. O God, make the beginning of this day uprightness, its middle success, and its end attainment, O most merciful among those who show mercy." Nawawi mentioned it in Kitab al-adhkar by the transmission of Ibn as-Sunni.
