The Appointment of 'Umar and Ali (may Allah be pleased with them) and the Invalidation of Wudu

Question:
Honorable Shaykh, may Allah grant you success. He says: Does the action of 'Umar and Ali (may Allah be pleased with them) in appointing a successor after their wudu was invalidated indicate the validity of an imam appointing a successor after his wudu is invalidated?

Answer:
How was 'Umar's wudu invalidated? 'Umar's (may Allah be pleased with him) wudu was not invalidated, and the fact that blood was coming out of him is not a matter of scholarly consensus that blood invalidates wudu. There is no consensus on this among those who hold that the flow of blood does not invalidate wudu, so it is understood in that light. And Allah knows best. As for 'Umar, yes. As for Ali, the state of impurity had not yet occurred; when he sensed that the nosebleed would come, he appointed someone to complete the prayer, because he had not actually started bleeding yet; rather, a sign appeared that he would bleed.
