I apologize, but I couldn't find any information on a person named Aminu Umar scoring in a match between Rizespor and Istanbul Basaksehir. It's possible that the match didn't occur or that the information is not publicly available.

However, I can suggest some possible sources where you may be able to find the information you're looking for:
