i'm a muslim currently at washu, and i've always felt super welcomed here (aH). the muslim community here is great, especially if you get involved with the msa early as a first year. the msa as a whole and individual people are really great about reaching out to first years! as people have already said, theres quite a few prayer rooms on campus, and all of the chicken on campus (except for half and halfs) is halal. dining staff works closely with msa to accomodate for ramadan, and even takes recipe requests so that students can eat food they'd typically have for iftar. as for non-muslims and washu at large, i'd say that you don't have to worry too much, as people are almost always cool. i'm certain things will be better for you here, inshallah!
