haqaiq-e-khilafat-o-malookiyaat seems to be just an attack on the book "khilafat-o-malookiyat" by abu aala maududi and also an attack on the person of maududi....
such books that r written only for confrontational purposes shud always be avoided as they r meant only and only to spread hatred, nothing beneficial in them....
I agree totally, but all such literature needs to be read and dissected so that it never can be used to spread propoganda ...simply ignoring it we will play right into the hands of these authors who always claim to represent a very revisionist version of history.
I will elaborate a bit more as this is important, every now and then extremists from both sides come up with outrageous claims and the orthodox /mainstream authorities ignore them for a while instead of countering them right away the result is that these beliefs are not effectively countered and become a part of mainstream.
Amongst shias same thing happened with additions to azan and ritual cursing of the shaikhyan which became popular around time of the safavids.Even though before that these things were considered extremists beliefs even by shia ulema.
Same thing unfortunately is happening in sunnis with literature of nawasib being popularized under the pretence of puritin islam.Where ALi & his sons/supporters are presented in a very negative light and legitamacy of his caliphate is being questioned.
