Entering the state of ihram for a second 'Umrah before shaving the head from the first 'Umrah

Question:
In the name of Allah, the Most Gracious, the Most Merciful. A questioner asks, saying in his question: A person entered the state of ihram for 'Umrah, and after completing the sa'y (walking between al-Safa and al-Marwah) and before shaving his head, he went directly to al-Tan'im and entered the state of ihram for an 'Umrah on behalf of one of his parents, then completed it and shaved his head. The question is: Does his forgetting to shave his head in the first 'Umrah have any effect on the second 'Umrah? And what is its effect on the first 'Umrah?

Answer:
He entered the state of ihram for the second 'Umrah before completing the first 'Umrah. Therefore, he must slaughter a sheep as a substitute for this; he slaughters a sheep in Makkah that is acceptable as an 'Id sacrifice and distributes it to the poor, the poor of the Haram, in place of the shaving he left off in the first 'Umrah.
