Q: What is the definition of Khawaarij?

Are there some Khawaarij or Khawaarij's ideologies in this time?

Q: What do the Ulama say about the Zaahiri school (literalist school of thought)?

Q: The Ahmaddiyah's prove the Mesiah to be Mirza Ghulam Ahmed becuase they say that in Sahih Bukhari Volume 4 Book 55 Hadith 648, Esa AS is described as having "red complexion and curly hair" but in the very next hadith (hadith 649) Rasulullah sallallahu alaihi wasallam describes Jesus, son of Mary to "having brown coloured skin and lank hair"

Can you please give me the tafseer of the two hadiths because Ahmadis claim that in both hadiths, Rasulullah sallallahu alaihi wasallam is describing Esa AS with 2 opposite descripitions. The Ahmadis claim that hadith 648 is descirbing the Prophet Esa and hadith 649 is describing the 'metaphorical' Esa AS (for them it's Mirza Ghulam Ahmed), can you please give some clarification?
