The one who said this is saying that Allah -azwj Majestic and Mighty Created the elite of His -azwj creatures, and the ones Beloved to Him -azwj , and His -azwj Prophets -as , and His -azwj Rasools -as , and the believing men, and the believing women, and the Muslim men, and the Muslim women unlawfully, and did not have the ability to Create them lawfully, and He -azwj has Taken the Covenant upon the Lawful, and the Purified, and the good.

And Allah -azwj has (even) Informed some of the animals that it should keep away from its sister. So when it descends upon it and when it find out that it is its sister, grabs it by its teeth until it cuts it, so it falls down dead.
