Departure From Mina: If you wish to leave Mina on the fourth day of Eid al-Adha (the Day of Sacrifice), you may depart after sunrise, and it does not matter at what hour you leave, whether you cast the stones (at the pillars) before or after noon. However, if you wish to leave on the first departure (the third day of Eid al-Adha), you must wait until the sun has passed its zenith (noon), as it is not permissible to leave before this time. If you remain in Mina until sunset, then you are not allowed to leave Mina and must stay until the fourth day of Eid al-Adha, which is the final departure. When you proceed to Mecca, do so while reciting Labbayk (Talbiyah), glorifying Allah سبحانه وتعالى, and supplicating. Upon reaching the Mosque of the Prophet (peace be upon him and his family), which is known as Masjid al-Hasba, enter it and lie on your back for a brief rest. For those who leave Mina on the first departure (the third day of Eid al-Adha), there is no obligation upon them to perform the ritual stoning (Hasba).
