Does Drinking Camel Milk Invalidate Your Wudu?
Question

I have read question 7103 , where it says that eating camel meat is one of the things that invalidate Wudu. Is it obligatory to do Wudu after drinking camel's milk too?
Praise be to Allah.Most of the scholars are of the view that it is not obligatory to do Wudu after drinking camel's milk. This is the well-known view of Imam Ahmad (may Allah have mercy on him). This is indicated by a number of things: 

The basic principle is that things do not break Wudu, and there is no authentic evidence to suggest that Wudu is invalidated by drinking camel's milk. 
The Prophet (peace and blessings of Allah be upon him) told some people who came to Madinah and got sick to drink camel's urine and milk. (Narrated by Al-Bukhari, 233 and Muslim, 1671) If drinking their milk invalidates Wudu , the Prophet (peace and blessings of Allah be upon him) would have told them about that. (See Al-Mughni, 1/245; Al-Insaf, 2/58; Ash-Sharh Al-Mumti`, 1/209) 

With regard to the Hadith narrated by Ahmad (18617) and Ibn Majah (496) from Usayd ibn Hudayr (may Allah be pleased with him) who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: “Do not do Wudu after (drinking) sheep's milk but do Wudu after (drinking) camel's milk,” and the Hadith narrated by Ibn Majah (497) from `Abdullah ibn `Umar (may Allah be pleased with him) who said: I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: “Do Wudu after (eating) camel meat and so not do Wudu after eating mutton; do Wudu after (drinking) camel's milk but do not do Wudu after (drinking) sheep's milk,” both of these Hadiths are inauthentic and cannot be quoted as evidence. They were classed as inauthentic by Al-Albani in Da`if Ibn Majah. 
Even if these Hadiths were authentic, the command mentioned therein could be understood as meaning that it is recommended to do Wudu after drinking camel's milk, so as to reconcile it with the Hadith quoted above.
