@Omar, I am aware of what Imam Al-Nawawi stated, and as I mentioned before I do not deny the fact that many great scholars believed that Al-Khidr (a) is alive.
However, my concern specifically is that this belief is solely based on people's own accounts of meeting with Al-Khidr. Now people can be deceived by Shaytan into thinking that the person they met was Al-Khidr. So is there any stronger proof of his existence.
Also, have you read Imam Asqalani's الزهر النضر في أخبار الخضر? Its a small booklet of ~ 48 pages.
He mentions the examples of Al-Nawawi, Umar bin Abdul Aziz, Ibn Al-Zubair and many many more...
And YET he argues against these in light of the Quran and Sunnah. So ultimately, the belief in the existence of Al-Khidr is not based on the two canonical sources, rather, it is based on the anecdotes of people. It can be in one of the following forms:
1) The 'man' himself stating that he is Al-Khidr
2) People saw a stranger who suddenly disappeared and they thought it was Al-Khidr
3) The person saw a (stranger) man and felt that it was Al-Khidr
4) The person met a stranger and people started saying to him that it must be Ilyas (a) or Al-Khidr
5) A third person relates the anecdote of a person who met the 'man' and decided that it was Al-Khidr
6) and so on...
Please read Asqalani's book, as he raises some really good points (book attached with this post).
@thetruth: I agree, its pointless to debate with 'the Shaykh' .
However, I am now curious myself, especially after reading Asqalani's book.
