Assalamu alaykum We shall take the advice of Mufti Desai sahib with deep respect. But the original booklet looks to be like "we are better than you" kind of attitude. If these authors of book would have a difference of opinion they would have approached the elders in Nizamuddin markaz. Compiling and publishing their opinion in an booklet format and the booklet reaching the laymen won't serve any purpose.
