Musannaf Ibn Abi Shayba 1:748

Yahya ibn Sa'id narrated to us, from al-Muhallab ibn Abi Habibah, that Jabir ibn Zayd was asked about a man who performed ghusl (full-body washing) for janabah (major ritual impurity), and he performed his wudu (ablution) for prayer, then he exited his place of washing. Does he need to perform wudu again? He said: "It suffices him to wash his feet."
