al-Sa'b bin Juthama bin Qays · The Book of Hajj

"The Messenger of Allah enter Ihram for 'Umrah and his companions enter Ihrahm for Hajj. He told those who did not have a Hadi with them to exit Ihram. Among those who did not have a Hadi with them was Tallah bin 'Ubaidullah and another man, so they exited Ihram."

This is 'Umrah that we have benefited from. Whoever does not have a Hadi with him, let him exit Ihram completely. Now 'Umrah is permissible during the months of Hajj."
