""Shariat can be fostered through the sword. Kufr and Islam are opposed to each other. The progress of one is possible only at the expense of the other and co-existences between these two contradictory faiths in unthinkable. The honor of Islam lies in insulting kufr and kafirs. One who respects kafirs, dishonors the Muslims. To respect them does not merely mean honouring them and assigning them a seat of honor in any assembly, but it also implies keeping company with them or showing considerations to them. They should be kept at an arm's length like dogs. ... If some worldly business cannot be performed without them, in that case only a minimum of contact should be established with them but without taking them into confidence. The highest Islamic sentiment describes that it is better to forego that worldly business and that no relationship should be established with the kafirs. The real purpose in levying jizya on them is to humiliate them to such an extent that, on account of fear of jizya, they may not be able to dress well and to live in grandeur. They should constantly remain terrified and trembling. It is intended to hold them under contempt and to uphold the honor and might of Islam. . . .Whenever a Jew is killed, it is for the benefit of Islam"."
