What is the ruling on prayer if blood comes out during the prayer, whether intentionally or unintentionally?

Question:
I say: Honorable Shaykh, may Allah grant you success. If a man prays and blood comes out of him during the prayer, whether its coming out was intentional or unintentional, what is the ruling on his prayer? And if the prayer is invalid, what is the ruling regarding my previous prayers? Do I have to repeat them? If the blood is a small amount

Answer:
then it does not harm. But if the blood is a lot, the safest course for you and to avoid the scholarly disagreement is to stop, work to stop the bleeding, then perform wudu' and repeat the prayer, or start the prayer anew. This is the safest for your conscience. As for the prayers that have passed, which were many, you are not required to repeat them. Yes. Allah the Exalted knows best, and may Allah send prayers and peace upon our Prophet Muhammad and upon his family and his companions.
