1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Mahbub from Hisham ibn Salim from Sawrah ibn Kulayb who has said the following: “I once asked abu ’Abd Allah عليه السلام, about the case of a woman experiencing Hayd (menses) if she must wash her clothes which she has used during her Hayd (menses). He (the Imam) said, ‘She must wash only what has come in contact with blood, and leave the rest alone I then said, ‘What happens if she perspires?’ He (the Imam) said, ‘Perspiration is not of Hayd (menses).’”
