Is an impediment that it is hoped will pass regarded as an excuse that makes it permissible to exit ihram during Hajj, for one who stipulated a condition when entering ihram?
Question

                Is it permissible for one who stipulated a condition when entering ihram, then he suffered a migraine and exhaustion and vomiting to exit his ihram?
Praise be to Allah.
		It is prescribed for the person who wants to enter ihram 
		for Hajj or ‘umrah to stipulate a condition when entering ihram, if he 
		fears that some impediment may prevent him from completing Hajj or 
		‘umrah. So he should say: “If something prevents me (from continuing), I 
		will exit ihram from the point where You have prevented me (from 
		continuing)” because of the report narrated by al-Bukhaari (5089) and 
		Muslim (1207), according to which the Prophet (blessings and peace of 
		Allah be upon him) said to Dubaa‘ah bint az-Zubayr, when she wanted to 
		do Hajj but was sick: “Go for Hajj but stipulate a condition and say: O 
		Allah, I will exit ihram from the point where You have prevented me 
		(from continuing, if some problem should arise).” 

	The benefit to the muhrim (pilgrim in ihram) from that is 
	that if some impediment arises that prevents him from completing his Hajj, 
	such as sickness or an accident, or he is prevented from entering Makkah for 
	some reason, then he may exit ihram and does not have to do anything further 
	– he does not have to pay any kind of compensation, or offer a sacrifice, or 
	shave his head. 

	But it is not permissible for the one who stipulated a 
	condition to exit ihram unless there is some impediment that is preventing 
	him from completing the rituals. As for temporary impediments that it is 
	hoped will pass, that is not regarded as an excuse that makes it permissible 
	to exit ihram, if waiting for it to pass will not cause undue hardship or 
	harm. 

	The excuse that you have mentioned, namely fainting, vomiting 
	and exhaustion is not regarded as something that would prevent one from 
	completing ‘umrah. In such cases it is possible to delay ‘umrah until the 
	impediments are gone. 

	And Allah knows best.
