[Machine] A doctor mentioned in the presence of the Messenger of Allah ﷺ a medicine and mentioned that the frog is used in it. So the Messenger of Allah ﷺ prohibited killing the frog.  

ذَكَرَ طَبِيبٌ عِنْدَ رَسُولِ اللهِ ﷺ دَوَاءً وَذَكَرَ الضُّفْدَعَ يُجْعَلُ فِيهِ فَنَهَى رَسُولُ اللهِ ﷺ عَنْ قَتْلِ الضُّفْدَعِ
