That the Messenger of Allah (ﷺ) said: "Kill snakes and kill Dhut-Tufyatain and Al-Abtar, because they blind the sight and cause abortions of fetuses."
That the Messenger of Allah (ﷺ) said: "Whoever kills a gecko in one strike, he has such and such reward, and if he kills it on the second strike, he will have such and such reward, and if he kills it on the third strike, then he has such and such reward."
That the Messenger of Allah (ﷺ) said: "Indeed there are others inhabiting your homes. So yell at them three times (to leave). If you see any of them after that, then kill them."
