Supplier and statistics

Hello. In the series “Doubt and Statistics” you said that the Sages forbade in the mishna at the end of Tractate Berakhot to pray about the past, because it is a prayer for a miracle (a physical nemna) and it is forbidden to pray about a miracle. But as I think the mishna implies that it is a logical nemna: “He was on the road, and heard a shrieking sound in the city, and said: “May it not be my family members” – this is a vain prayer.” It seems from the mishna that the person is not praying that God will perform a miracle and correct reality, but rather that it is a request that reality from the start not occur in a certain way that would include the members of his family, even though the reality has already occurred. In analogy to a person who sees on the news that a stabbing attack has occurred and prays: May it not be my family members who were stabbed.
