Is Wudu' performed for the Funeral Salah valid for the obligatory Salahs?

(Part No. 4; Page No. 71)  Fatwa no. 14683 A: One day we followed a funeral procession to the graveyard. We performed the Funeral Salah (Prayer) over the deceased and buried him. Upon returning, the Maghrib (Sunset) Prayer was due. We entered a Masjid (mosque) to perform the Salah, but a man said that whoever accompanied the deceased to the grave should perform Wudu' (ablution), since the Wudu' performed for the Funeral Salah is not valid for the obligatory Salahs. We differed regarding this issue, whereas other attendants agreed with him. Please elaborate on this issue. May Allah's Peace, Mercy, and Blessings be upon you.

A: It is permissible for one who performs Wudu' for a supererogatory Salah to offer obligatory Salahs with this Wudu'. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
