We replied, "This white man reclining on his arm." They then addressed him" - Sahih Bukhari 1:3:63 (read more)

"It is also incumbent upon Muslims that they should not accept from them [Jews] victuals with which they had come into contact, such as distillates, which cannot be purified. If something can be purified, such as clothes, if they are dry, they can be accepted, they are clean...It would also be better if the ruler of the Muslims would establish that all infidels could not move out of their homes on days when it rains or snows because they would make Muslims impure." - Muhammad Baqir Majlesi
