Musannaf Ibn Abi Shaybah

Ibrahim says that in such a case, another Hadi becomes obligatory upon him.

Hazrat Ata also says the same.

Hazrat Mujahid says that if someone shaves his head before offering the Hadi sacrifice, then another Hadi becomes obligatory upon him.

Hasan also says the same.

Hazrat Alqamah says that in this case, offering a sacrifice (dam) is obligatory. Hazrat A’mash says that I mentioned this to Ibrahim, and he said that it is narrated in the same way from Hazrat Ibn Abbas (may Allah be pleased with them both).

Ibrahim says that such a person should either slaughter a goat, or feed six needy people, or fast for three days.
