Abstain from doing the following things:
On reciting the Talbia with the NIyyat of Umrah (or Haj) you have entered into the state of Ihram. Now until you have performed the Umrah on reaching Makkah you cannot put on a stitched dress, or cover your head or face at any time, or wear shoes that enclose the elevated bone in the middle of the upper part of the foot, or have a hair-cut ( you cannot shave or pull out even a single hair from any part of your body), or cut your nails, or use perfume, or have sexual intercourse, or do anything which is likely to arouse passions or be sexually gratifying in any other way, cannot kill a living being including a mosquito, bed-bug, and lice. (In the case of women the only difference is that they can wear stitched clothes. It is also not necessary for them to remain bare-headed but they must keep the face uncovered, i.e, they cannot wear a veil or cloak to cover their faces. If they come face to face with men who are not related to them they should hide their faces behind a fan or something else.
All these restrictions will remain in force until you have reached Makkah and performed the Umrah. For those intending to perform the Qiran or Ifrad Haj, i.e, who will do the Niyyat of performing the Haj also with the Umrah in the same Ihram or of performing the Haj alone, the aforementioned restrictions will continue till the end of the Haj.
The first act of the Haj or Umrah is the wearing of Ihram. Though you were in the course of the pilgrimage from the moment you had set out from your home, you had up to now performed none of the rites of the Haj or Umrah. Now, with the putting on of the Ihram, so to say, the process of the Haj or Umrah has begun. A Haj or Umrah pilgrim enters into the act of the Haj or Umrah with the putting on of Ihram and recitation of Talbia in the same way in which a person offering the Namaz enters into the act of Namaz with the formulation of intention and the saying of Takbir Tehrima. It is now your duty to pay due heed to all the restrictions of Ihram and abstain from doing things that are prohibited during that state. Do not quarrel with anyone at all whatever the provocation, suppress your anger, and recite the Talbia frequently especially when mounting upon or dismounting from anything and meeting anyone and after each Namaz and at mornings and evenings.
