حَدَّثَنَا حَسَنٌ حَدَّثَنَا زُهَيْرٌ عَنْ سُهَيْلِ بْنِ أَبِي صَالِحٍ عَنْ أَبِيهِ عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ مَنْ قَتَلَ الْوَزَغَ فِي الضَّرْبَةِ الْأُولَى فَلَهُ كَذَا وَكَذَا حَسَنَةً وَمَنْ قَتَلَهُ فِي الثَّانِيَةِ فَلَهُ كَذَا وَكَذَا حَسَنَةً وَمَنْ قَتَلَهُ فِي الثَّالِثَةِ فَلَهُ كَذَا وَكَذَا قَالَ سُهَيْلٌ الْأُولَى أَكْثَرُ.
English Translation
The Messenger of Allah (peace be upon him) said: "Whoever kills a gecko with the first strike will have such-and-such good deeds. Whoever kills it with the second strike will have such-and-such good deeds. Whoever kills it with the third strike will have such-and-such good deeds." Suhayl said: The first is the most (in reward).
