Musannaf Ibn Abi Shaybah

Hazrat Aisha (may Allah be pleased with her), daughter of Talha (may Allah be pleased with her), narrates from Hazrat Aisha (may Allah be pleased with her), the Mother of the Believers (may Allah be pleased with her), that she killed a snake. Then, in a dream, it was said to her, "By Allah, you have killed a Muslim." She replied, "Then why did it enter the chambers of the wives of the Prophet (peace and blessings be upon him)?" It was said to her that it only comes to you when you are in your clothes. So she woke up in fear and ordered twelve thousand (coins) to be spent in the way of Allah.
