Question: If I was performing the tamattu’ hajj, and [bought a sacrificial ticket by] paying the bank the price of the sacrifice, and they told me the slaughter shall take place on the first day of ‘Eed (10th Dhul-Hijjah) – am I thereby discharged from the state of ihraam after stoning al-jamarah [al-kubraa], the tawaaf al-ifaadhah and the sa’ee?
Response: Slaughtering the sacrificial animal has no connection with being discharged from the state of ihraam, [even] if he brought it (the sacrificial animal) with him from the haram; it is permissible for him to discharge himself from the state of ihraam without having slaughtered the sacrificial animal. Rather that which is required to [qualify] be[ing] discharged from the state of ihraam is stoning [al-jamarah al-kubraa], shaving [the head] or cutting the hair short, the tawaaf al-ifaadhah, and the sa’ee; [the fulfilment of] these rites are connected to [qualifying for] being discharged from the state of ihraam. As for slaughtering the sacrificial animal, then this has no connection with being discharged from the state of ihraam.
