Usamah ibn Zayd · General Behavior (Kitab Al-Adab)

When the Messenger of Allah (ﷺ) sat talking (to the people), he would often raise his eyes to the sky.

I went to the prophet (May peace be upon him) when he was in a skin tent. He then mentioned something similar to it.

The Messenger of Allah(ﷺ) prohibited killing the jinnan(small snakes) that are in the house, except the one which have two streaks and the one with small tail, for they obliterate the eyesight and cause miscarriage.
