I think you need to consider Sidi Haddads comments with a pinch of salt. He has also attacked other Ahlus Sunnah scholars on their beleifs and been soundly refuted. You think it is just the Murabitun he disagrees with? I assure you not, there are other Maliki Ulema he has said incorrect things about, i dont want to spread fitnah but i have the proof, so i ask you

do you really want to get involved in this conversation?

Sidi Haddad could not answer the comments other respected and noble Ulema made about him, indeed if he could have he would probably have no doubt done so already. So if he couldnt, then what makes you think you can, on behalf of him on Maliki issues? Its probably better you and i spent our time on more important issues of our faith.
