Hadith on Dua: Declaring Allah is One, morning and evening

Anas ibn Malik reported: The Prophet, peace and blessings be upon him, said, “One should say in the morning: O Allah, we have reached morning, calling you to witness, calling the carriers of your throne to witness, your angels, and all of creation that you are Allah and none has the right to be worshiped but you alone, without any partners, and that Muhammad is your servant and messenger. If he says this, Allah will forgive him for what he did during the day. If he says it in the evening, Allah will forgive his sins during the night.

عن أنس عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ مَنْ قَالَ حِينَ يُصْبِحُ اللَّهُمَّ أَصْبَحْنَا نُشْهِدُكَ وَنُشْهِدُ حَمَلَةَ عَرْشِكَ وَمَلَائِكَتَكَ وَجَمِيعَ خَلْقِكَ بِأَنَّكَ اللَّهُ لَا إِلَهَ إِلَّا أَنْتَ اللَّهُ وَحْدَكَ لَا شَرِيكَ لَكَ وَأَنَّ مُحَمَّدًا عَبْدُكَ وَرَسُولُكَ إِلَّا غَفَرَ اللَّهُ لَهُ مَا أَصَابَ فِي يَوْمِهِ ذَلِكَ وَإِنْ قَالَهَا حِينَ يُمْسِي غَفَرَ اللَّهُ لَهُ مَا أَصَابَ فِي تِلْكَ اللَّيْلَةِ مِنْ ذَنْبٍ
