Article ٩٢- As we said before, it is an obligatory precaution that the pilgrim does not tie loincloth around the neck, but tying that around waist, especially when it is needed, also tying Rida around or using pin for fixing the position of Rida or Izar has no problem, but it is better to renounce that acts. And the method, which is common among some of Hajjis, of putting a piece of stone on one side of clothing and fastening it with a rubber strap or a string to another side is also permitted.
Article ٩٣- Wearing all kinds of sewed clothes is permitted for women, except gloves, which are not permitted to wear.
Article ٩٤- The atonement of wearing sewed cloths in cases of necessity is a sheep, but if this act is performed because of ignorance or forgetfulness, then it has no atonement.
