Do nosebleeds nullify Wudoo’ ?

Question 24Do nosebleeds nullify Wudoo’ (ablution) and Salaah (Prayer) or not?

Answer: Impure matters that come out through any opening from human body other than the urethra and anus, but are neither urine nor stool, such as nosebleeds, vomit, wounds, and the like do not nullify Wudoo’ as long as they are not in much quantity, for the Hadeeth reported by ‘Aboo Al-Dardaa’ that the Prophet (peace be upon him) once vomited and then he performed Wudoo’ (ablution). According to Ibn `Abbaas, (may Allaah be pleased with him both): “If the blood flows in large quantities, it (Wudoo’) should be repeated.” more here.
