Assalamualaikum wa rehmathullahi wa barakatuhu... my question is why people doesn't agree for inter-caste marriages in islam. as Allah(s.w.t) mention clearly all are equal then some people didn't agree for khan or syed's marriage... I want to know the reason behind this...

Truly, there is no cast in islam. Just like Christianity and Buddhism. But people follow it because of influence of sub continent culture.
