Masruq (may Allah have mercy on him) narrates from Sayyidah Aishah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) married one of his wives while in the state of ihram, and had cupping done while in the state of ihram.
It is also narrated through Ibrahim, from al-Aswad, from Aishah. Abu Ali al-Hafiz said: Both chains are mistaken; what is preserved is from Mughirah, from Shibak, from Abu al-Duha, from Masruq, from the Messenger of Allah (peace and blessings be upon him) as mursal.
