Is the Hadith: "Congregational prayer is led by the most pious man in the congregation" authentic?

The virtue of congregational prayer is established by authentic hadiths, among them the hadith stating the superiority of congregational prayer over individual prayer by twenty-seven degrees. As for the hadith mentioned in the question, it has no chain of narration, and it was only mentioned by some scholars without attributing it. The Sunnah has indicated that a greater number of worshippers is better, and that praying with the righteous and scholars is better due to the comprehensiveness of the supplication and the swiftness of its answer. In conclusion, the mentioned hadith has no origin from the Prophet, peace and blessings be upon him, and every person will have what they strove for. So, whoever excels in their prayer, their excellence is for them, and whoever does evil, their evil is upon them. The point is that every worshipper will be held accountable for their own actions, not for the actions of others.
