Root Islamic Education is a good book, probably Shaykh Abdalqadir's best, if you ignore certain passages such as this. I dislike the Murabitun for many reasons, but I think it is unfair for people to take these quotes out of context and post them on this forum to stir up trouble. Shaykh Abdalqadir made this statement when he was fairly young, and though they may seem to smack of ta'assub, his actions for the past thirty years show that he respects and has nothing but good dealings with the Hanafis and Shafi'is. And to clarify, he did not say that these Imams had "no usul", he is merely expressing an opinion that the Maliki madhhab has the most sound and complete usul which is a totally valid opinion for someone to hold about their madhhab.
