Ibrahim (may Allah be pleased with him) said regarding a man who has a nosebleed or an involuntary occurrence during prayer: "He should leave without speaking, except to remember Allah, perform ablution, return to his place, and complete the remainder of his prayer, counting what he has already prayed. If he spoke, he must start over." [Narrated by Muhammad in "Al-Athar."]
In a narration by Ibn Abi Shaybah from Ali (may Allah be pleased with him): "If a man has a nosebleed or vomits during prayer, let him perform ablution without speaking and resume his prayer." The narrators of this chain meet the conditions of authenticity.
