public testimony and witness

إِن نَّقُولُ إِلَّا ٱعْتَرَىٰكَ بَعْضُ ءَالِهَتِنَا بِسُوٓءٍ ۗ قَالَ إِنِّىٓ أُشْهِدُ ٱللَّهَ وَٱشْهَدُوٓا۟ أَنِّى بَرِىٓءٌ مِّمَّا تُشْرِكُونَ

We only say that some of our gods have possessed you with evil [i.e., insanity]." He said, "Indeed, I call Allāh to witness, and witness [yourselves] that I am free from whatever you associate with Allāh

قَالَ مَوْعِدُكُمْ يَوْمُ ٱلزِّينَةِ وَأَن يُحْشَرَ ٱلنَّاسُ ضُحًى

[Moses] said, "Your appointment is on the day of the festival when the people assemble at mid-morning."

قَالُوا۟ فَأْتُوا۟ بِهِۦ عَلَىٰٓ أَعْيُنِ ٱلنَّاسِ لَعَلَّهُمْ يَشْهَدُونَ

They said, "Then bring him before the eyes of the people that they may testify."
