When this came up a couple week ago, I found examples of people using "medieval Arabic", "Medieval Africa", and even more specifically "Medieval Somalia". See https://news.ycombinator.com/item?id=35984909 https://news.ycombinator.com/item?id=35984909 for links. These are used in modern scholarly writing, like "The Medieval Archaeology of Somaliland" from 2002 at https://doi.org/10.1093/acrefore/9780190854584.013.566 https://doi.org/10.1093/acrefore/9780190854584.013.566 and "China in medieval Indian imagination: “China”-inspired images in medieval South Asia" from 2021 at https://doi.org/10.1017/S1479591421000176 https://doi.org/10.1017/S1479591421000176 . However, as others have commented, just because people do use them isn't enough to say if that's the primary form to refer to that period of time.
