1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam and Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr all from ‘Abd Allah ibn Yahya al-Kahiliy who has said the following: “I once said to abu ‘Abd Allah عليه السلام, that today women have found a certain manner of hair dressing. One of them can find a certain device made of wool which a hair dresser uses along with certain fragrance, then places in a thin piece of fabric, then ties it up with a pin and places it over her head and then she may experience sexual relation. He (the Imam) عليه السلام, said, ‘Women of earlier times would only decorate their hairs at the front of their head. If they may need to take Ghusl (bath), instruct them to allow water to reach their head and wring the decorated hair so water reaches it; when water reaches it then it is not harmful. 5 I then asked about Hayd (menses) and he (the Imam) said, ‘Women experiencing Hayd (menses) must reduce it (such decoration of hairs) a great deal.’”
