Is it obligatory to maintain the order when making up missed prayers?

Question : He says that the Prophet (peace and blessings be upon him) made up the missed prayers in order during the Battle of the Trench; he made them up in order. Is this making up of missed prayers in order obligatory, or is it recommended? Is it a mere action, or is it an action of obedience to a command?

Answer : Yes, the second one, not the first? The second one, because he (peace and blessings be upon him) said: “Whoever sleeps through a prayer or forgets it, let him pray it when he remembers it.” So he (peace and blessings be upon him) was occupied with something other than the prayer, and when he was free from his occupation, he prayed it in order. And he said: “Pray as you see me praying.” For this reason, the stronger opinion among the views of the scholars is that maintaining the order in making up missed prayers is obligatory, and that it is not permissible to pray one prayer before another. However, if he forgets or is ignorant, his prayer is valid.
