It is mentioned in a hadith that Nabi (sallalaahu alayhi wassallam) said, ” When a female child is born, Allah Ta’ala sends His angels to that house. They come to the dwellers of the house and pray that peace may be upon them, The angels then cover the newly born girl in the shadow of their wings and caressing the head of the baby with their hands they say that, this is a weak and frail person, whoever will bear the responsibility of cherishing her will go on having the blessing of Allah Ta’ala as long as that person remains alive.” ( Al-Mojam al – Saghir li Tabrani).
