The mother of Abd ar-Rahman ibn al-Awf {May Allah be pleased with them} said:

When the Prophet Muhammad ﷺ {was born and} dropped into my hands, he ﷺ sneezed and I heard a voice saying: May Allah have mercy upon you!’ Then the entire horizon from the east to the west became illuminated for me whereby I was able to see the castles of the Romans.
