In Arabic:

‎اَللّٰهُمَّ إِنِّيْ أَصْبَحْتُ أُشْهِدُكَ ، وَأُشْهِدُ حَمَلَةَ عَرْشِكَ وَمَلَائِكَتَكَ وَجَمِيْعَ خَلْقِكَ ، أَنَّكَ أَنْتَ اللّٰهُ لَا إِلٰهَ إِلَّا أَنْتَ وَحْدَكَ لَا شَرِيْكَ لَكَ ، وَأَنَّ مُحَمَّدًا عَبْدُكَ وَرَسُوْلُكَ.

Allāhumma innī aṣbaḥtu ush-hiduk, wa ush-hidu ḥamlata ʿarshik, wa malā’ikatika wa jamīʿa khalqik, an-naka Anta-llāhu lā ilāha illā Anta waḥdak, lā sharīka lak, wa anna Muḥammadan ʿabduka wa rasūluk.

O Allah, I have entered the morning, and I call upon You, the bearers of Your Throne, Your angels and all creation, to bear witness that surely You are Allah. There is no god worthy of worship except You Alone. You have no partners, and that Muḥammad ﷺ is Your slave and Your Messenger.
