al-Mughira bin Maqsam المغيرة بن مقسم · General Behavior (Kitab Al-Adab)

He who believes in Allah and in the last day should honour his guest; he who believes in Allah and in the last day should not harm his neighbor; he who believes in Allah and in the last day should speak good or keep silence.

give it a warning for three days; if it appears to you after that, then kill it, for it is only a devil.
