Obey orders from the prophet without hesitation or doubt.

This hadith is about the importance of following the orders of the Prophet Muhammad (peace be upon him). In this particular case, he ordered Umm Sharik to kill a chameleon. This was because it had blown fire on Prophet Ibrahim. It is important for Muslims to follow the orders of their prophet and not question them, even if they do not understand why they are being asked to do something. The lesson here is that we should trust in Allah and His messenger and obey his commands without hesitation or doubt.
