Did the Imam lead the Dhuhr and Asr prayers, shortened and audibly, on the Day of Arafah in the year 1421 AH?

What the Imam did by combining Dhuhr and Asr prayers on the day of Arafah is correct. However, reciting aloud (jahr) is incorrect, as the Prophet (peace be upon him) recited silently (sirr) during Dhuhr prayer on the day of Arafah. Your prayer is valid, and the Imam acted out of forgetfulness. Scholars have differed on the necessity of performing the prostration of forgetfulness (sujud (definition) as-sahw) for one who recites aloud where silence is required, or silently where loudness is required. There is latitude in this matter due to the absence of a specific text addressing it.
