Musannaf Ibn Abi Shaybah

Yahya bin Abdullah bin Abi Qatadah narrates that my mother told me that her father used to say that one of Abu Qatadah’s sons came on Friday after performing ghusl and combing his hair. He asked, “Did you perform ghusl for Jumu’ah?” He replied, “No, this was the ghusl of janabah.” Abu Qatadah said, “Then perform ghusl for Jumu’ah as well.”
