​
Dhū l-Ḥijjah (Arabic: ذو الحِجَّة) is the last month in Hijri calendar and one of the Haram months and months of hajj. Many practices have been reported for this month in Shi'a and Sunni hadiths. This month is the only permissible time for ihram of hajj al-tamattu'. Literally, Dhu l-Hijja means "owner of hajj" which indicates the close relation of the month to hajj. Hajj rituals usually start in the 9th of Dhu l-Hijja, and finish in the 13th of this month.

Importance
This month is one of the eminent and great months of the year according to Islamic teachings. The first ten days of it, are very well known because of performing hajj rituals during this time. Eid al-Adha, Eid al-Ghadir, the Event of Mubahala and many other events have happened in this month. It is been narrated in hadiths that the ten nights which God has sworn to them in Quran 89 are the ten nights of the first ten days of this month. Moreover, in Quran 22 (Sura al-Hajj), verse 28, Allah has talked about the "Known Days" in which the faithful must remember Allah.[3] One of the most prevalent interpretations for these glorified and great "Known Days" is the first ten days of Dhu l-Hijja. The Prophet (s) said, "For Allah, there is no time purer and greater in reward than these ten days."
In addition to the first ten days of this month which is called "Known Days" in the Qur'an, some other days of this month have been given special names in hadith such as Yawm al-Tarwiya (the day of taking water) for the eighth, the Day of 'Arafa and Yawm al-Mashhud (the day of witnessing) for the ninth, Eid al-Adha or Yawm al-Nahr (the day of sacrificing camels) for the tenth, Ayyam Ma'dudat (appointed days)[6] and Ayyam al-Tashriq (the days of shining) and Ayyam Mina (the days of Mina) for the eleveth to the thirteenth, Yawm al-Qarr (the day of settlement) for the eleventh, Yawm al-Nafr and Yawm al-Nafr al-Awwal (the day of first migration) for the twelfth, and Yawm al-Nafr al-Thani (the day of second migration) and Yawm al-Sadar and al-Hasaba for the thirteenth.
