Is it permissible to supplicate with "Our Lord, judge between us and our people in truth, for You are the best of those who judge" during the Friday sermon, and is this considered a supplication against the people, based on the interpretation of some scholars?

The meaning of "iftah" (open) in supplication is "iqdi" (judge/decide). So the meaning of "Our Lord, judge between us and our people with truth" (ربنا افتح بيننا وبين قومنا بالحق) is "judge between us and them with truth," meaning grant victory to the one who is in the right and punish the one who is in error. This supplication is against those among the people who are in error, and it should only be invoked when there is someone who deserves it, as the prophets did with their people. The repetition of this supplication by the preacher every Friday without justification is not appropriate; rather, it is an aggression in supplication. The Prophet, peace and blessings be upon him, said: "There will be people who commit aggression in supplication," and he recited the verse: "Call upon your Lord humbly and privately; indeed, He does not like aggressors" (ادْعُوا رَبَّكُمْ تَضَرُّعًا وَخُفْيَةً إِنَّهُ لَا يُحِبُّ الْمُعْتَدِينَ). The preacher should be advised gently to refrain from this supplication unless there is a need that warrants it.
