SubhanAllah i love this naat!! And Syed Fasihuddin has got to be one of the best naatkhawans in the world!! May Allah exalt his status. Here is his recitation at the Victoria Park Conference you mentioned (although its not the best quality): http://www.youtube.com/watch?v=5MJl0HuTp_Y Wish i could have been there :'(
i reluctantly went along to the na'at conference at VP mosque a few months ago and wish to mention the superlative rendition of this na'at by sayyid fasihuddin suharwardi. it was the highlight of the event. he is a proper na'at khwan and one of the original reciters. he is not just a "pesha war" na'at khwan who does it for money. here is one rendition from him and the one at VP sounded even better. it happened to be 25th safar that day too! this is another rendition by him.
