Fiqh 4 — Menstruation & Special Rulings الحيض

Ḥayḍ durations · what's prohibited · ḥayḍ vs istiḥāḍah vs nifās · cat hair · covering the head in the toilet · Exam: Sunday 8:00

The numbers (1 day min / 15 days max / 6–7 usual, 15-day minimum purity) and the ḥayḍ vs istiḥāḍah distinction carry this lesson. The two handout rulings are likely short answers.

1 · Menstruation (Ḥayḍ) الحيض

Meaning: linguistically "flowing"; in the Sharʿ, natural blood from the innermost womb after puberty, in health, at known times. It necessitates ghusl.

Signs of puberty (bulūgh)

  • Nocturnal emission (iḥtilām) — male & female.
  • Menstruation — for females.
  • Otherwise, completing 15 lunar years. (Emission/menses can begin after completing 9 lunar years.)

Durations

  • Minimum: 1 day & night.
  • Maximum: 15 days & nights.
  • Common (usual): 6 or 7 days.
  • Purity (ṭuhr) between cycles: minimum 15 days; no maximum (may go a year or more).

2 · Istiḥāḍah & the three bloods

  • Istiḥāḍah (irregular bleeding): blood seen for less than the minimum (under 1 day & night) or more than the maximum (over 15 days). It is illness-blood from a vein (al-ʿādhil).
  • Istiḥāḍah invalidates wudū but does NOT require ghusl and does NOT prevent prayer or fasting. She washes, binds the area, makes wudū for each obligatory prayer, then prays.
  • Distinguishing ḥayḍ from istiḥāḍah: by colour and intensity — menstrual blood is dark and thick/recognisable.
BloodWhat it isGhusl?Stops prayer/fasting?
ḤayḍMonthly natural blood (1–15 days)Yes, when it endsYes
IstiḥāḍahIllness blood, outside ḥayḍ limitsNoNo (wudū per prayer)
NifāsPostnatal (childbirth) bleedingYes (a cause of obligatory ghusl)Yes
Scope note: the course lists nifās as a cause of obligatory ghusl and treats it like ḥayḍ, but the handout does not give specific nifās day-counts — so don't quote a nifās maximum.

3 · What is prohibited during Ḥayḍ

  1. Prayer — and she does NOT make up missed prayers.
  2. Reciting the Qurʾān, touching or carrying the muṣḥaf.
  3. Staying in the mosque (passing through is allowed if no fear of soiling it).
  4. Ṭawāf around the Kaʿbah.
  5. Fasting — and she MUST make up the missed fasts (qaḍāʾ).
  6. Intercourse and direct contact between the navel and the knees.
Memory hook: fasts are made up, prayers are not. Once the menses ends, fasting becomes obligatory even before ghusl (but she cannot pray until she does ghusl).

4 · Two special handout rulings

Cat hair

  • Majority (Ḥanafī, Mālikī, Ḥanbalī): cat hair is pure — whether attached or fallen off while the cat is alive (the cat itself is pure: "It is not impure; it is one of those that move among you").
  • Shāfiʿī: detached cat hair is impure if it separates while the cat is alive ("whatever is cut from a living creature is dead"); the cat's body is pure during life, but they recommend avoiding the detached hair.
  • Preferred view: the majority — pure in all cases (ease, and the explicit hadith).

Covering the head when entering the toilet

  • No authentic hadith from the Prophet ﷺ establishes it (the narrations are weak).
  • Authentically reported from the Salaf — Abū Bakr covered his head out of modesty.
  • Some scholars (al-Nawawī, al-Ghazālī, etc.) called it a recommended etiquette (mustaḥabb).
  • Not obligatory — no sin or dislike on whoever leaves it; a praiseworthy adab of modesty for whoever does it.
Lock the ḥayḍ numbers first — every one is a one-mark gift on the paper.

NatureMonthly naturalIllness (a vein)Childbirth
Requires ghusl?YesNoYes
Stops prayer/fasting?YesNo — wudū each prayerYes
Tell apart byColour & intensity (ḥayḍ = dark, thick); <1 day or >15 days = istiḥāḍah

Forbidden in Ḥayḍ & the make-up rule

  1. Prayer — not made up. · Fasting — must be made up.
  2. Reciting / touching / carrying the muṣḥaf.
  3. Staying in the mosque (passing through OK). · Ṭawāf.
  4. Intercourse & contact between the navel and the knees.
