1. The two 'Eed days namely: al-Fitr ad al-Adh.haa; as 'Umar ibn al-Khattaab (radhi-yAllahu 'anhu) said:
    "Verily the Messenger of Allah prohibited fasting on these two days the day of al-Fitr from Ramadan and the other day on which you eat whilst carrying out your (hajj) rites" i.e. 'Eed al-Adh.haa
    [Transmitted by Muslim]
  2. The days of Tashreeq and they are the 11th 12th and 13th days of Dhul-Hijjah.
    The Messenger of Allah (sal-Allahu 'alayhe wa sallam) sent 'Abdullaah ibn Hudhaafah (radhi-yAllahu 'anhu) around Minaa saying:
    "Do not fast these days for indeed they are the days for eating and drinking and remembering Allah ('Azza wa Jall")
    [Saheeh transmitted by Ahmad]
    And the ones excused from this prohibition are those who are performing the Tamattu' or al-Qiraan hajj but have no means to offer the obligatory sacrifice.
  3. The menstrual and post partum bleeding days with respect to women.
    The Messenger of Allah (sal-Allahu 'alayhe wa sallam) said:
    "Is it not that when she is on her menses she does not pray nor fast? Then this is the deficiency in her religion?"
    [Transmitted by al-Bukhaaree]
  4. The wife fasting whilst in the presence of her husband unless she has sought his permission.
    The Messenger of Allah (sal-Allahu 'alayhe wa sallam) said:
    "A woman is not to fast whilst in the presence of her husband except with his permission not including (the fast of) Ramadan"
    [The authenticity of this narration has been agreed upon by al-Bukhaaree and Muslim]
