Aisha (RA)’s Example (Hadith No. 313)
Hadith no. 312 is a repeat. Read it here.
In the last Hajj of Allah’s Apostle, I assumed the Ihram for Hajj along with Allah’s Apostle. I was one of those who intended Tamattu’ (to perform Hajj and ‘Umra) and did not take the Hadi (animal for sacrifice) with me. I got my menses and was not clean till the night of ‘Arafa. I said, “O Allah’s Apostle! It is the night of the day of ‘Arafat and I intended to perform the Hajj Tamattu’ with ‘Umra. Allah’s Apostle told me to undo my hair and comb it and to postpone the ‘Umra. I did the same and completed the Hajj. On the night of Al-Hasba (i.e. place outside Mecca where the pilgrims go after finishing all the ceremonies Hajj at Mina) he (the Prophet) ordered ‘Abdur Rahman (‘Aisha’s brother) to take me to At-Tan’im to assume the lhram for’Umra in lieu of that of Hajj-atTamattu’ which I had intended to perform.
Reference: Hadith no. 293.
Hajj can be performed in the state of menstruation, so don’t take those hormones that postpone (and disturb) your menstrual cycle. If faced with such a situation, delay the Umrah like Aisha (RA) did and perform the Hajj. Do your Umrah right after you’re purified. No hassle. :)
