the Muslim who has entered ihraam for Hajj or ‘Umrah to omit any of their actions, or to do any of the things that are forbidden whilst in ihraam which may detract from his Hajj or ‘umrah

Is it permissible for the pilgrim to appoint someone to stone the
jamaraat on his behalf on the day of Eid or the second day, then go
back to his homeland?.
Praise be to Allaah.
In His Holy Book, Allaah commands us to Hajj and'Umrah properly, as He
says (interpretation of the meaning): "And perform properly (i.e. all
the ceremonies according to the ways ofProphet Muhammad صلى الله عليه
وسلم), the Hajj and 'Umrah (i.e. the pilgrimage to Makkah) for Allaah"
[al-Baqarah 2:196]. Performing them properly cannot be doneunless one
does them sincerely for the sake of Allaah and following the Messenger
of Allaah (peace and blessings of Allaah be upon him). So it is not
permissible for the Muslim who has entered ihraam for Hajj or 'Umrah
to omit any of their actions, or to do any of the things that are
forbidden whilst in ihraam which may detract from his Hajj or 'umrah.
The one who appoints someone to stone the jamaraat during the days of
al-Tashreeq or on one ofthe days of al-Tashreeq and leaves on the day
of sacrifice is regarded as one who is mistaken andwho is mocking the
rituals prescribed by Allaah. The one who appoints someone to stone
the jamaraat on his behalf on the eleventh or twelfth during the days
of al-tashreeq and does thefarewell tawaaf so that he can leave
quickly has gone against the teachings of the Messenger of Allaah
(peace and blessings of Allaah be upon him) and what he has enjoined
of performing the rituals inthe proper order. He has to repent and
seek forgiveness for that, andthe one who does that has to offer a
sacrifice for not staying overnight in Mina, and a sacrifice for not
stoning the jamaraat for which he appointed a proxy and left, and a
third sacrifice for the farewell tawaaf even if he circumambulated the
Ka'bah when he left, because he did the tawaaf at the wrong time, for
the farewell tawaaf can only be doneafter one has finished stoning the
jamaraat.
And Allaah is the Source of strength. may Allaah send blessings and
peace upon our Prophet Muhammad and his family and companions.
