What should someone do who did not observe the proper sequence in making up missed prayers, such as making up Maghrib, then Asr, then Dhuhr?

Scholars have differed on the obligation of arranging missed prayers (Qada'): The Hanafis and Malikis are of the opinion that it is obligatory if the missed prayers are few, while the Hanbalis hold that it is obligatory in all cases. The Shafi'is, however, view it as recommended in all cases. If one prayed without arranging them due to ignorance, their prayer is valid. It is advised to arrange them in the future as a precaution, as there is no explicit evidence for the obligation of arrangement.
