It is permissible for the Muslim to perform many Salahs, five or more, with the same Wudu', even if a person does not intend to do so upon making Wudu'. (Part No. 6; Page No. 203) He may also perform as many Nafilah (supererogatory) prayers as he wishes along with the obligatory ones with the same Wudu' as long as it is not nullified according the consensus of scholars, due to the authentic Hadith narrated from the Prophet (peace be upon him) in this regard.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
