What is the solve of controversy on Camel's urine

I think it was only for a special tribe which was found in the Hadith. It is not quoted if it was for the whole Muslims ummah it not. Reference:Sayyiduna Anas (Allah be pleased with him) narrates that some people came from (the tribe of) ‘Ukl or ‘Urayna and became ill in Madinah. The Messenger of Allah (Allah bless him and grant him peace) commanded them to go to the milk-camels and to drink their urine and milk (for their treatment). (Sahih al-Bukhari, no: 231)

In a Nutshell: The wording regarding camel urine in some hadith is not the Prophet's words (شرب أبوال الإبل) but the wording of the narrator. There are authentic ahadith which mention some people got sick and asked the Prophet (saw) for advice. He told them to go and: "فشربتم من ألبانها" drink camel milk.

One of the narrations adds "and their urine". This additional wording is from the narrator and not the wording of the Prophet. The Prophet only advised them to drink camel milk.

Al-Nasai has an entire chapter on this in his Sunan. It was narrated Anas said:

"Some people from Uraynah came to the Messenger of Allah (saw), but the climate of Al-Madinah did not suit them. The Messenger (saw) said to them: 'Why don't you go out to our camels and drink their milk?'" The narrator Qatadah added the wording regarding urine. Abu Dawud in his Sunnan narrates hadith without this additional wording stating this wording regarding urine was not uttered by the Prophet (saw).

Ibn Hajar and Khatib al-Baghdadi also note all narrations cite the drinking of milk. One cites Abu Qatadah as adding this wording.

My question is that,is that prescription was special... is it alsoprescription for Muslim Ummah to do so?

Yes, it was for specific tribe. Scholars believe that some people from the tribe had disease which had no other cure available. So camel urine was prescribed.

Is this for ummah how can I know this is accurate.......how to use in present.

Well I don't know what you mean by accurate, if you are talking about the accuracy of Hadith then many scholars argue that this is an abrogated hadith . If you are talking about consumption then only a doctor can say which cure is accurate or not and usually in present times no urine is used as cure.

You know some people are mocking....

Those who mock believe that it is by Hadith that camel urine is a Sunnah which is wrong as any urine is considered impure/Haram, unless it is used as medicine when no other alternative is available.
