Shortening Salah by residents

Q 1: A resident shortened and combined the Zhuhr (Noon) and `Asr (Afternoon) Prayers with some travelers forgetfully, then he remembered what he did before the Maghrib (Sunset) Prayer. What should he do? Should he repeat the whole Salah (Prayer) or just the missed two Rak`ahs (units of Prayer) of each Salah? Please, advise.

A: He should hasten to repeat the whole two Salahs because he should not have shortened them since he is a resident, and shortening Salah is permissible for travelers only.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
