Musannaf Ibn Abi Shaybah 13532 — A man who enters ihram for Hajj

Ikrimah said: When a person enters ihram for Hajj and is then prevented, he must offer a sacrificial animal (hady). Then, if the way opens up for him, he should turn it into an Umrah and perform Hajj in a later year, but no sacrifice is due from him. If he delays it until the Hajj has taken place, he owes both a Hajj and an Umrah the following year, and whatever sacrificial animal is available to him; and if he does not find a sacrificial animal, he should fast three days in such a way that the last fast falls on the Day of Arafah.
