The table below shows the Gregorian dates of Hajj of recent years (the dates correspond to 9 Dhul-Hijjah of Hijri calendar). Prospective dates are approximate:  "Fiqh" literature describes in detail the manners of carrying out the rites of Hajj, and pilgrims generally follow handbooks and expert guides to successfully fulfill the requirements of Hajj. In performing the rites of Hajj, the pilgrims not only follow the model of Muhammad, but also commemorate the events associated with Abraham. When the pilgrims reach the appropriate "Miqat" (depending on where they have come from), they are believed to enter into a state of holiness – known as "Ihram" – that consists of wearing two white seamless cloths for the male, with one wrapped around the waist reaching below the knee and the other draped over the left shoulder and tied at the right side; wearing ordinary dress for the female that fulfills the Islamic condition of public dress with hands and face uncovered; taking ablution; refraining from certain activities such as clipping the nails, shaving any part of the body, having sexual relations; using perfumes, damaging plants, killing animals, covering head (for men) or the face and hands (for women); getting married; or carrying weapons. The "Ihram" is meant to show equality of all pilgrims in front of God, with no difference between the rich and the poor. Donning such unsewn white garments entirely is believed to distance man from material ostentation, and engross him in a world of purity and spirituality, since clothes are believed to show individuality and distinction and create superficial barriers that separate individuals. The garments of Ihram are seen as the antithesis of that individualism. "Ihram" clothing is also a reminder of shrouds worn after death. On the 8th Dhu al-Hijjah, the pilgrims are reminded of their duties. They again don the Ihram garments and confirm their intention to make the pilgrimage. The prohibitions of Ihram start now. The 8th day of Dhu al-Hijjah coincides with the Tarwiyah Day. The name of Tarwiyah refers to a narration of Ja'far al-Sadiq. He described the reason that there was any water at Mount Arafat in the 8th day of Dhu al-Hijjah. If pilgrims wanted to stay at Arafat, he would have prepared water from Mecca and carried it by themselves to there. So they told each other drink enough.
