Is it lawful for a person to deputize another to throw the pebbles and travel before being thrown?

A: Allah (Glorified be He) orders in the Glorious Qur'an that Hajj and `Umrah (lesser Hajj) should be perfected. (Part No. 11; Page No. 289) He (Glorified be He) says: And perform properly (i.e. all the ceremonies according to the ways of Prophet Muhammad صلى الله عليه وسلم), the Hajj and ‘Umrah (i.e. the pilgrimage to Makkah) for Allâh. Hajj and `Umrah can not be considered complete unless they are made sincerely for the sake of Allah (Exalted be He) and according to the Sunnah (whatever is reported from the Prophet, peace be upon him). Thus, it is not permissible for a Muslim who entered Ihram (ritual state) for Hajj or `Umrah to violate any of their rituals or to do any prohibited thing that decreases the reward thereof. Accordingly, whoever deputizes someone to throw their Jamarat during the Days of Tashriq (11th, 12th and 13th of Dhul-Hijjah) or one of them, and then departs on the Day of Nahr (the Day of the Festival of the Sacrifice) is mistaken and regarded as being heedless of the rites prescribed by Allah (Exalted be He). Similarly, if someone deputizes another person to throw the Jamarat of the 11th or the 12th day of Dhul-Hijjah and performs Tawaf-ul-Wada` (circumambulation of the Ka`bah on leaving Makkah) to hasten their travel, they are violating the Prophet's guidance and instructions regarding the performance and order of the rituals of Hajj. They have to make Tawbah (repentance to Allah) and Istighfar (seeking forgiveness from Allah) for doing this. Moreover, they have to offer a sacrifice for not spending the night at Mina, a second sacrifice for not throwing the Jamarat that they deputized others to throw on their behalf and traveled, and a third sacrifice because they performed Tawaf-ul-Wada` at the wrong time for this Tawaf is to be performed after throwing the Jamarat.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
