Bismillaah Al-Hamdulillaah
Wa 'alaykum u salam wa rahmatullaahi wa baarakatu, ya Abu Soufyaan,
It was recorded on the 29th of Rajab, 1423 (corresponding with 10/6/2002) and posted on SalafiTalk a few days later by student of knowledge 'Abdul-Ilah Lahmami here -------> http://www.salafitalk.net/st/viewmes...um=6&Topic=322. And as you'll read in the latter posts, a brother named Aboo Ibraheem said he recorded this talk on MP3, in response to someone asking if anyone had recorded it.
As for the name of the lecture or tape it was recorded on, Allaah knows best.
Baarak Allaahu feek, ya Abu Soufyaan.
