The Ruling on the Order of Making Up the Five Daily Prayers

Question:
I arrived at New York Airport from Los Angeles on my way to Riyadh, and I had not yet prayed the Dhuhr and Asr prayers. I found a group praying, so I joined them, but they were praying Maghrib and were in the second rak'ah. I prayed Maghrib with them and made up the rak'ah I had missed. Then I prayed Isha with them, and after that I prayed Dhuhr and Asr on my own. Is what I did valid? If not, what must I do? And is there anything required of me regarding what I did? I ask for your guidance. May Allah reward you with good.

Answer:
If the questioner was forgetful that he had the Dhuhr and Asr prayers to make up when he prayed Maghrib and Isha with the people, then there is no blame on him. However, if he was remembering that he had not prayed Dhuhr and Asr when he prayed Maghrib and Isha with them, then he must repeat the Maghrib and Isha prayers after he prays Dhuhr and Asr; because the order between the five daily prayers is obligatory. And success is from Allah.
