Abu Huraira reported Allah's Messenger (ﷺ) as saying:He who killed a gecko with the first stroke for him is such and such a reward, and he who killed it with a second stroke for him is such and such reward less than the first one, and he who killed it with the third stroke for him is such and such a reward less than the second one

This hadith has been reported on the authority of Abu Huraira through another chain of transmitters (and the words are):- He who killed a gecko with the first stroke for him are ordained one hundred virtues, and with the second one less than that and with the third one less than that

Abu Huraira reported Allah's Messenger (ﷺ) as saying (that he who kills a gecko) with the first stroke there are seventy rewards for him
