Ali bin Hujr bin Iyas bin Maqatil علي بن حجر بن إياس بن مقاتل · The Book on Hajj

"A woman from Khath'am said: 'O Messenger of Allah! My father has lived until Allah has made Hajj obligatory, and he is an elderly man who is not able to sit on the back of a camel.' So he (pbuh) said: 'Perform Hajj for him.'"

"Whoever performs Hajj to the House, then let the last of their acts be at the House, except for menstruating women. The Messenger of Allah gave them permission (to leave)." (Sahih Mawquf)

The Messenger of Allah said: "Whoever assumes Ihram for Hajj and Umrah, then it is acceptable for him to perform one Tawaf and one Sa'I for them both, until he exits Ihram for both of them together."
