Muwatta Malik, 859

Yahya related to me from Malik that he had heard the people of knowledge say, "Someone who dedicates a sacrificial animal for compensation or as part of the hajj should not eat from it." Yahya related to me from Malik that he had heard that Umar ibn al-Khattab and AIi ibn Abi Talib and Abu Hurayra were asked about a man who had intercourse with his wife while he was in ihram on hajj. They said, "The two of them should carry on and complete their hajj. Then they must do hajj again in another year, and sacrifice an animal." Malik added that AIi ibn Abi Talib said, "When they then go into ihram for hajj in a future year they should keep apart until they have completed their hajj
