Umm Kurz told that she heard Allah's Messenger ﷺ say, “Let the birds stay in their roosts.”* She told that she also heard him say, “Two sheep are to be sacrificed for a boy and one for a girl, but it does you no harm whether they are male or female.” *Either that they are not to be molested, or that they are not to be disturbed for the purpose of taking omens. Abu Dawud transmitted it. Tirmidhi and Nasa’i transmit it from “two sheep” to the end, Tirmidhi saying this is a sahih tradition.
