Sahih Al Bukhari (316)

عن عائشة قالت: أهللت مع رسول الله صلى الله عليه وسلم في حجة الوداع، فكنت ممن تمتع ولم يسق الهدي، فزعمت أنها حائض، ولم تطهر حتى دخلت ليلة عرفة، فقالت: يا رسول الله، هذه ليلة عرفة، وإنما كنت تمتعت بعمرة؟ فقال لها رسول الله صلى الله عليه وسلم: (انقضي رأسك، وامتشطي وأمسكي عن عمرتك). ففعلت، فلما قضيت الحج، أمر عبد الرحمن، ليلة الحصبة، فأعمرني من التنعيم، مكان عمرتي التي نسكت.

`A'ishah (may Allah be pleased with her) narrated: In the last Hajj of Allah’s Messenger (peace be upon him) I assume the Ihram for Hajj along with Allah’s Messenger (peace be upon him). I was one of those who intended Tamattu‘ (to perform Hajj and `Umrah) and did not take the Hadi (animal for sacrifice) with me. I got my menses and was not clean till the night of `Arafah I said: "O Allah’s Messenger (peace be upon him)! It is the night of the day of `Arafat and I intended to perform the Hajj Tamattu` with `Umrah." Allah’s Messenger (peace be upon him) told me to undo my hair and comb it and to postpone the `Umrah. I did the same and completed the Hajj. On the night of Al Hasba' (i.e. place outside Makkah where the pilgrims go after finishing all the ceremonies of Hajj at Mina) he (the Prophet (peace be upon him)) ordered `Abdur-Rahman (`A'isha’s brother) to take me to At-Tan`im to assume the Ihram for `Umrah in lieu of that of Hajj-at-Tamattu` which I had intended to perform .
