Ibrahim used to say about the person whose nose starts to bleed during prayer that he should go and perform ablution, then, as long as he has not spoken, he should complete the same prayer, and if he has spoken, he should repeat the prayer.

Hazrat Ata also says the same.

Ibrahim, regarding the person who vomits or whose nose starts bleeding during prayer, says that he should go and perform ablution. If, during this time, he does not speak, he should complete the same prayer, and if he speaks, he should start the prayer anew. Ibrahim used to say about the person who goes to urinate or defecate that he should go, perform ablution, and start the prayer anew.

Ibrahim says that the predecessors were very strict regarding urine and feces, and considered them more severe than semen and blood.

Hazrat Mak'hool says that if a man has a nosebleed during prayer, he should go and perform ablution and complete the remainder of his prayer, provided he has not spoken to anyone. If his ablution is invalidated, then he should perform ablution again and also repeat the prayer.

Yazid bin Abdullah bin Qasit says that during prayer, Sa'id bin al-Musayyib had a nosebleed. He went to the house of Umm al-Mu'minin Umm Salamah, performed ablution, did not speak to anyone during this time, and returned to complete the same prayer.

Hazrat Aamir says that if your ablution breaks during prayer, then perform ablution and complete the remaining prayer, even if you have engaged in conversation.

Hazrat Ali (may Allah be pleased with him), regarding a person who vomits or suffers from nosebleed during prayer, says that he should go and perform ablution and complete his prayer, as long as he has not spoken.

It is also narrated from Hazrat Abdullah in the same way, however, vomiting is not mentioned in it.
