Regarding killing snakes
حَدَّثَنَا ابْنُ السَّرْحِ، وَأَحْمَدُ بْنُ سَعِيدٍ الْهَمْدَانِيُّ، قَالاَ أَخْبَرَنَا ابْنُ وَهْبٍ، قَالَ أَخْبَرَنِي أُسَامَةُ، عَنْ نَافِعٍ، فِي هَذَا الْحَدِيثِ قَالَ نَافِعٌ ثُمَّ رَأَيْتُهَا بَعْدُ فِي بَيْتِهِ .
The tradition mentioned above has also been transmitted by Nafi through a different chain of transmitters. In this version Nafi said: After that I saw it again in his house.
