Narrated from Sayyidah Aisha (may Allah be pleased with her) that newborn children would be brought to her and she would pray for blessings for them. Once, a child was brought. When she was about to place his pillow, there was a razor underneath it. She inquired about the razor, and they said: "We keep it for protection from jinn." Sayyidah Aisha (may Allah be pleased with her) picked up the razor and threw it away, forbade them from doing this, and said: "The Messenger of Allah (peace and blessings be upon him) disliked bad omens and he hated them." And Sayyidah Aisha (may Allah be pleased with her) also forbade this.
