Can You Change Clothes in Ihram?
Question

When performing Hajj and staying overnight in Mina I had a "wet dream" (out of my control). When I woke up I immediately made ghusl and washed and changed my ihram. Did I do the correct thing and is my Hajj still valid?
Praise be to Allah.Yes, it is permissible for the pilgrim in ihram to change his ihram clothes . We have previously quoted the fatwa of the Standing Committee in the answer to question no. 26722 . Here we will add the fatwa of Shaykh Ibn ‘Uthaymin (may Allah have mercy on him). 
Shaykh Muhammad ibn Salih al-‘Uthaymin said: 
“It is permissible for the muhrim (pilgrim in ihram) who is doing Hajj or ‘Umrah, male or female, to change the clothes in which he or she entered ihram and to put on different clothes, if the other clothes are things which it is permissible for the pilgrim in ihram to wear.” (Al-Manhaj li Murid al-‘Umrah wa’l-Hajj (no. 5).
