Article ٤٦- Those who do not pass Miqats should become Muhrim whenever they reach to a place parallel to one Miqat and it is not necessary to go to one of first quintet Miqats, and if they pass two places parallel to two of Miqats, they should wear Ihram in the first place that is parallel to the first Miqat.
Article ٤٧- When the pilgrim surely knows the location of the place parallel to Miqat or he/ she asks the location from informed people, it is enough for wearing Ihram from that place, but if he/ she has doubt about this matter and there is no way of research for finding the answer, then it is better that he/ she performs Nazr of Ihram before reaching that place and becomes Muhrim from there.
Article ٤٨- Whenever a pilgrim is passing a direction, which there is no place parallel to one of Miqats, he/ she should go to one of Miqats and become Muhrim from there as a precaution; and if this not also possible, then he should become Muhrim from a place that there is a possibility of being parallel to one of Miqats in his/ her opinion and then renews his/ her Ihram after reaching the closest point to Haram( around Mecca ), it means that the pilgrim make intention again and says" Labbayk".
