2. A number of our people have narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from ‘Abd Allah ibn Bukayr from ‘Abd al-Rahman ibn ’A‘yan who has said the following: “I once said to him (the Imam) (a.s.), that the wife of ‘Abd al-Malik gave birth. He instructed her to wait for the number of days of her Hayd (menses), then instructed her to take Ghusl (bath), fill up, wear two clean clothes and perform Salah (prayer). She said, ‘My soul does not feel happy to enter the Masjid; so allow me to stay out of the Masjid and prostrate in it.’ He (the Imam) said, ‘The Messenger of Allah had issued such commandments and said, ‘Bleeding stops and she finds cleanliness,’ and Ali (a.s.), before you had issued such commandments; once bleeding stops the woman finds herself clean. What did the woman (of your companion) do?’ I replied, ‘I do not know.’” (‘Abd al-Malik mentioned is perhaps ‘Abd al-Malik ibn ’A‘yan, according to al-Dhakhirah).

3. Ali ibn Ibrahim has narrated from his father in a marfu‘ the following: “A woman once asked abu ‘Abd Allah (a.s.), saying, ‘I would, because of childbirth, wait for twenty days and they gave a fatwa to wait for eighteen days. Abu ‘Abd Allah (a.s.), asked, ‘Why did they give a fatwa for eighteen days?’ A man then said it is because of the Hadith from the Messenger of Allah who said to Asma’ bint ‘Umays for the birth of Muhammad ibn abu Bakr. Abu ‘Abd Allah (a.s.), then said, ‘Asma’ asked the Messenger of Allah after eighteen days. Had she asked before, the Messenger of Allah would ask her to take Ghusl (bath) and do what a Mustahadah is required to do.’”
