For the introduction of 'Umrah into Hajj does not yield any benefit for it beyond what the first contract yielded; thus, it is invalid, just as if one were to hire someone for a task and then hire him for it a second time within the same period. The reverse of this is the introduction of Hajj into 'Umrah.

673 - Issue; He said: "And whoever has sexual intercourse before stoning the Jamrat al-'Aqabah, the Hajj of both of them is corrupted, and he is liable for a sacrificial camel (badana) if he coerced her, and there is no blood-sacrifice (dam) upon her."

There are three sections in this issue: The first section is that sexual intercourse before stoning the Jamrat al-'Aqabah corrupts the Hajj, and there is no difference between before the standing at Arafat and after it. This is the view of Malik and al-Shafi'i. The scholars of opinion (Ashab al-Ra'y) said: If he has sexual intercourse after the standing, his Hajj is not corrupted, because of the Prophet's saying (may God bless him and grant him peace): "Whoever catches Arafat, his Hajj is complete." And because he is safe from the expiration of time (fawat), so he is safe from corruption, just as after the first stage of exiting ihram. Our argument is that a man asked Ibn 'Abbas and 'Abd Allah ibn 'Amr, saying: "I have had relations with my wife while we were both in the state of ihram." They both said to him: "You have corrupted your Hajj." And they did not ask the inquirer for details. This was recorded by al-Athram. And because it is sexual intercourse that occurred during a complete state of ihram, so it corrupted it, just like before the standing. It differs from the state after the first stage of exiting ihram, for the ihram is not complete there. What is meant by the tradition is the safety from the expiration of time, and safety from the expiration of time does not necessitate safety from corruption. By the evidence of 'Umrah, one is safe from its expiration but not safe from its corruption. Ahmad said: "I do not know anyone who said that his Hajj is complete, other than Abu Hanifah. He says: Hajj is 'Arafat, so whoever stands there, his Hajj is complete." This is only like the saying of the Prophet (may God bless him and grant him peace): "Whoever catches a rak'ah of the prayer, he has caught the prayer."
