One who performed Hajj but did not perform Sa'y, and one who performed Sa'y without Tawaf

The questioner:
Honorable Shaykh, a man performed Hajj and did not perform sa'y because he was ignorant, and another performed Hajj as an individual (ifrad) and performed sa'y without tawaf. What is the ruling on them?

The Shaykh:
Number.

The questioner:
He performed Hajj and did not walk between al-Safa and al-Marwah.

The Shaykh:
But he must perform the Sa'y; he should return and perform it. If he had sexual intercourse, he must also sacrifice an animal in Makkah and distribute it to the poor. If he did not have sexual intercourse, it is sufficient for him to go and perform the Sa'y and the farewell Tawaf when he wants to leave.

The questioner:
And the other one performed Hajj alone (ifrad) and walked between al-Safa and al-Marwah without circumambulating the Ka'bah.

The Shaykh:
He added that he performed the Sa'y of Ifadhah; he goes and comes back for the Sa'y of Ifadhah. If the bleeding was due to sexual intercourse, he must also bring [a sacrifice]. No, he does not exit the state of ihram, because he has not exited the state of ihram by stoning the pillars or shaving his head. Yes.

The questioner:
Some jurists say that he should go and perform an 'Umrah, and then come back.

The Shaykh:
No, that is not appropriate. If he performs an 'Umrah, it does not contradict what is required, and it is sufficient for him to do so, as he still has the obligation remaining to complete it. Yes.
