Hazrat Umar, Hazrat Ali (may Allah be pleased with him), and Hazrat Ibn Abbas (may Allah be pleased with them) say regarding the person who sends a sacrificial animal (Hadi) that he should abstain from those things from which a person in the state of Ihram abstains, and it is not necessary that he does not recite the Talbiyah. And Hazrat Jafar says that the people to whom he is sending the Hadi, he should fix a day with them and take a promise, then when that promised day arrives, he should abstain from all those things from which a person in Ihram abstains.
