Hazrat Tawus says that only the first animal should be sacrificed.

Hazrat Qabeesah bin Dhuwaiyb asked Hazrat Abu Bakr bin Abu Jahm? He replied, "Slaughter both animals together."

Hazrat Ata says that if the first animal (the lost one) was nafl (supererogatory), then he will slaughter both; and if the first animal was wajib (obligatory), then he will slaughter only that one, and regarding the second animal, it is up to him—if he wishes, he may slaughter it, and if he wishes, he may not.

Hasan and Hazrat Ata state that if the animal for a voluntary sacrifice is lost and he buys another in its place and puts a collar on it as well, then now he will slaughter both. And if he has not yet put a collar on it, then if he wishes, he can sell it.

It is narrated from Hazrat Abdur Rahman bin Sabit that the Holy Prophet, peace and blessings be upon him, said: Whoever departs from this world without having performed the obligatory Hajj (Hajj of Islam), and he was not prevented by any illness, compulsion, or a tyrant ruler, then he may die in whatever state he wishes, whether as a Jew or as a Christian.

Hazrat Al-Aswad said to a wealthy person that if you die without performing Hajj, I will not offer your funeral prayer.

Hazrat Mujahid bin Rumi narrates that I asked Hazrat Saeed bin Jubair, Hazrat Abdur Rahman bin Abi Laila, and Hazrat Abdullah bin Ma’qil about a person who, despite having the means, dies without performing Hajj. Hazrat Saeed said,“For him is the Fire.”Hazrat Ibn Ma’qil said,“He died in a state of disobedience to Allah.”And Hazrat Ibn Abi Laila said,“If his guardian performs Hajj on his behalf, I hope (i.e., he will be saved from the punishment of Allah).”

15057 - Ibn (Mu'qqal) said (1): He died while he was disobedient to Allah (2).

15058 - Ibn Abi Layla said: I hope that his guardian will (perform Hajj) (1) on his behalf.

Hazrat Saeed bin Jubair says that if my wealthy neighbor dies without performing Hajj, I will not offer his funeral prayer.
