And Yahya ibn Yahya narrated to us, saying: Khalid ibn Abdullah informed us, from Suhayl, from his father, from Abu Hurayrah, who said: The Messenger of Allah, peace and blessings be upon him, said: "Whoever kills a gecko with the first blow will have such-and-such good deeds, and whoever kills it with the second blow will have such-and-such good deeds, less than the first, and if he kills it with the third blow, he will have such-and-such good deeds, less than the second."
