It is narrated from Hazrat Salam bin Miskeen that Hazrat Jabir bin Zaid and Hasan were asked: A woman has taken an oath that she must send a Hadi (sacrificial animal)? Hazrat Jabir bin Zaid said: If she is wealthy, she should send a cow, and if she is poor, she should send a goat. And Hasan said: It is the expiation for an oath; she should fast for three days.

12996 - Al-Hasan said: The expiation for an oath is to fast three days.

Hasan says that if a person says, "I have a Hadi (sacrificial animal) upon me," or "I have made a vow," then this is an oath.

Hazrat Ikrimah says that if a person swears by a camel or Hadi, then this is one of the ways of Satan.

It is narrated from Hazrat Ibn Abbas (may Allah be pleased with them both) that if a person says, "It is obligatory upon me to offer Hadi," then he should not send less than a goat.

Hazrat Hakam and Hazrat Hammad say: When a person says, "Sending Hadi is obligatory upon me," and does not specify anything, then this is an oath.

Hazrat Dhahhak says that when a person says that sending a Hadi (sacrificial animal) is obligatory upon me and does not specify its name, then he may send whatever Hadi he wishes, even if it is just a fawn (young deer).
