A man of Banu Amir said: Messenger of Allah, my father is very old, he cannot perform hajj and umrah himself nor can be ride on a mount. He said: Perform hajj and umrah on behalf of your father.
Sunan Abi Dawud Book 11, Hadith 90
← Previous Hadith ‘Abd Allah bin Abbas said Al Fadl bin Abbas was riding the Camel behind the Apostle of Allaah(ﷺ). A woman of the tribe of Khath’am came seeking his (the Prophet’s) decision (about a problem relating to Hajj). Al Fadl began to look at her and she too began to look at him. The Apostle of Allaah(ﷺ) would turn the face of Fadl to the other side. She said Apostle of Allaah(ﷺ) Allaah’s commandment that His servants should perform Hajj has come when my father is an old man and is unable to sit firmly on a Camel. May I perform Hajj on his behalf? He said yes, That was at the Farewell Pilgrimage.

Sunan Abi Dawud Book 11, Hadith 89 Next Hadith → The Prophet (ﷺ) heard a man say: Labbayk (always ready to obey) on behalf of Shubrumah. He asked: Who is Shubrumah? He replied: A brother or relative of mine. He asked: Have you performed hajj on your own behalf? He said: No. He said: perform hajj on your own behalf, then perform it on behalf of Shubrumah.
