My finger bleed very little, but I didn't wash it until the next day, and then I made ablution and prayed, while I was praying, I remember that I still had this wound that I haven't washed, but I decided to continue to pray, after I finished, I checked my wound, it has been covered by my skin (almost healed), the color of the wound already became brown (i think it's the process of the skin covering the wound). I perceived that there is not blood anymore on the outside, maybe it's because the skin covered it, do I need to redo my salah?
