The Role of Angels in Witnessing

شَهِدَ ٱللَّهُ أَنَّهُۥ لَآ إِلَـٰهَ إِلَّا هُوَ وَٱلْمَلَـٰٓئِكَةُ وَأُو۟لُوا۟ ٱلْعِلْمِ قَآئِمًۢا بِٱلْقِسْطِ ۚ لَآ إِلَـٰهَ إِلَّا هُوَ ٱلْعَزِيزُ ٱلْحَكِيمُ

Allāh witnesses that there is no deity except Him, and [so do] the angels and those of knowledge - [that He is] maintaining [creation] in justice. There is no deity except Him, the Exalted in Might, the Wise.
