Therefore, if a person had made the intention for ihram and wore the two pieces of cloth but, before reciting the Talbiyah, performed one of the acts prohibited during ihram, he had not done any wrong and he would not incur any kaffarah. Rule 7: The obligation is to recite Talbiyah once; it is though mustahab to repeat it as many times as one possibly can. As a matter of precaution, a person performing Umrat-ut-Tamatu’ must stop the recitation of Talbiyah on sighting the houses of old Makkah.
The point for those arriving at Makkah, via its upper approaches, from the route of Madinah is Madniyeen. The point for those arriving via its lower approaches is Aqabat Thi Tawa. As a matter of precaution too, those performing Umrat-ul-Mufradah must stop the recitation on entering the Haram, if they have arrived from outside Makkah. Those who have gone outside Makkah, only to wear the ihram from Adnal Hil, should cease the recitation on sighting the Holy Ka’aba.
Those performing all types of Hajj must stop the recitation at Zawaal (noon) on the day of Arafat. Rule 8: If after wearing the two pieces of cloth for ihram but before departing from the Meqat, a person entertains a doubt as to whether or not he had recited the Talbiyah, he should recite it; if the doubt arises after the recitation as to whether he had recited it correctly, he should resolve that he had.
Third: Wearing ihram garments After taking off all that which is not permitted to wear during ihram, it is obligatory to wear the two pieces of ihram. Children are exempt from this rule as they can delay wearing ihram till Fakh if they take that route. Apparently, there is no certain way of wearing them. So, one can wear one of the pieces of cloth around the waist in whatever way he wishes and place the other piece over the shoulders, or use it as a robe.
However, as a matter of precaution, the two pieces should be worn in the traditional way. Rule 1: Most evidently, wearing the two pieces of cloth is obligatory as a matter of obedience in worship, yet it is not a condition for the validity of the ihram. Rule 2: As a matter of precaution, it is necessary that the piece of cloth worn round the waist should cover the portion from the navel to the knee; the other piece should cover both the shoulders, arms and a considerable part of the back.
As a matter of obligatory precaution, both the pieces must be worn before the intention and Talbiyah.
