What is the ruling regarding the prayer of a girl whose husband consummated the marriage with her and she bled after the breaking of her hymen, and is it necessary for her to perform ablution immediately before prayer?

If the blood discharged due to a man's intercourse with his wife is not considered menstrual blood (hayd), then it nullifies ablution (wudu'). The woman must wash it off and purify herself from it before praying. If it does not stop, she should perform ablution, use a piece of cloth (as a protective measure), and pray. However, if the blood is menstrual blood, then it has its own specific rulings.
