1. A number of our people have narrated from Ahmad ibn Muhammad ibn ‘Isa from Ali ibn Ahmad ibn ‘Ushaym from Ahmad ibn Muhammad ibn abu Nasr who has said the following: “I once asked abu al-Hassan , about the minimum and maximum period of time of Hayd (menses). He (the Imam) said, ‘It is three days and its maximum is not more than ten days.’”
