It is narrated from Abu Umamah (may Allah be pleased with him) that Umar (may Allah be pleased with him) led people in prayer while he was in a state of major impurity (janabah). He repeated the prayer, but the people did not repeat it. Ali (may Allah be pleased with him) said to him: "Those who prayed with you should have repeated the prayer." Umar said: "They then returned to the opinion of Ali."
