he might be referring to the hadith about not living so close to the kuffar that you can see their fires. cant find the hadith but im sure you know which one i mean. i would really like to know the explanation of this hadith and what the ulama say about it.
salaam i cant remember where i read the hadith but the words where along the lines ' whomsoever lives amonst the kuffar 1) is not amongst us or 2) i have no concern from them 'i cant rememember the which of the 2 endings it was. as for mufti rasheed (ra) i beleive he said living amongst the kuffar is like sending sheep to a pack of wolves
