Sahih al-Bukhari 5566

It is related from ash-Sha'bi that Masruq went to 'A'isha and said to her, "Umm al-Mu'minin, there is a man who sends the sacrificial camels to the Ka'ba while he remains in his city and gives instructions that his camels be garlanded and then he remains in ihram from that day people come out of ihram." He said, "I could hear her clap from behind the screen. Then she said, 'I used to plait the garlands of the sacrificial camels of the Messenger of Allah, may Allah bless him and grant him peace. He would send his camels to the Ka'ba, but nothing was unlawful to him which is lawful for a man to do with his wife until the people returned [i.e. he did not assume a state of ihram].'"
