Hazrat Saeed, may Allah have mercy on him, was asked that two men saw a bird; one said that if this is not a crow, then his wife is thrice divorced, and the other said that if this is not a pigeon, then his wife is thrice divorced. So he narrated the saying of Hazrat Qatadah, who used to say that when the bird flew away and it was not known what it was, then neither this one should go near his wife nor that one should go near his wife.
