Al-Adab Al-Mufrad #914

'Alqama reported that 'A'isha used to go to children when they were born and make supplication for them. She came to a child and removed its pillow and found a straight razor under his head. She asked about the razor and they said, "We put it there against the jinn. She took the razor, threw it away and forbade them to use it. She said that the Messenger of Allah, may Allah bless him and grant him peace, disliked and hated seeing bad omens in things. She forbade doing that.
