Islam:
Muhammed's grandfather was described as Black, and the Arabs of that time period were Black and brown (mixed). Arabs had various shades of Blackness to refer to. They, for the most part, were melanated peoples. Muhammed has been described as tanned, brown, red, and black, depending on which sources you go with.
Persians/Indo Europeans intermixed with Black/brown Arabs after Islam started to spread; their descendants are white supremacys depiction of Arabs/Muslims.
Christianity:
Not sure if Paul was Black but hes at least mixed, and Christianity started in Palestine. And obviously Jesus was Black or mixed. He and the fam hid in Egypt amongst other Egyptians. Most Egyptians back then were still Black and brown.
Judaism:
The easiest to figure out. It was started by a Black man (Moses), in Egypt (Africa), borrowing African traditions (circumcision) and guidelines (42 negative confessions), that existed before religion existed elsewhere (including Summer)
