This rule was abrogated by Muhammad, who said it was permissible to leave the state of Ihram if one intended to attend Hajj. and this relaxation became known as "joy" (Arabic: Mut'ah) or more distinctly, the "joy of pilgrimage", Mut'ah of Hajj or in Arabic :Hajj al-Tamattu. This is not mentioned in the Qur'an, rather it is a part of the Sunnah.
