اللَّهُمَّ أَمْسَيْنَا نُشْهِدُكَ وَنُشْهِدُ حَمَلَةَ عَرْشِكَ وَمَلاَئِكَتَكَ وَجَمِيعَ خَلْقِكَ بِأَنَّكَ الله لاَ إِلَهَ إِلاَّ أَنْتَ وَحْدَكَ لاَ شَرِيكَ لَكَ وَأَنَّ مُحَمَّدًا عَبْدُكَ وَرَسُولُكَ
Allahumma amsaina nush-hiduka wa nush-hidu ḥamalata arshika wa mala’ikataka wa jami`a khalqika bi-annaka Allah, la ilaha illa anta, waḥdaka la sharika laka, wa anna Muḥammadan abduka wa rasuluk
O, Allah, we have reached the evening, calling You to witness, and calling the carriers of Your Throne to witness, and Your angels, and all of Your creation, that You are Allah, none has the right to be worshipped but You, Alone, without a partner, and that Muhammad (S.A.W.) is Your slave and Your Messenger.
