وَعَن ميمونةَ أَنَّ فَأْرَةً وَقَعَتْ فِي سَمْنٍ فَمَاتَتْ فَسُئِلَ رَسُول الله صلى الله عَلَيْهِ وَسلم فَقَالَ: «ألقوها وَمَا حولهَا وكلوه» . رَوَاهُ البُخَارِيّ
Maimuna said that when a mouse fell into some clarified butter and died God's messenger was asked about it and replied, "Throw it and what is round it away and eat what is left."
Abu Huraira reported God’s messsenger as saying, "When a fly alights in anyone’s vessel he should plunge it all in and then throw it away, for in one of its wings there is a cure and in the other disease."
Ibn ‘Umar told of hearing the Prophet say, "Kill snakes, kill those which have two streaks and those with small tails, for they obliterate the eyesight and cause miscarriage." ‘Abdallah said that while he was chasing a snake and trying to kill it Abu Lubaba called to him not to kill it, but he replied that God's messenger had given command that snakes should be killed. He then said that he had later prohibited killing house-snakes, for they are resident jinn.
I was on the expedition when the army had to beat leaves off trees for food and Abu ‘Ubaida was placed in charge. We suffered severe hunger, and then the sea cast up a dead fish the like of which we had never seen before, called the spermaceti whale, and we ate of it for half a month. Abu ‘Ubaida took one of its bones and a rider was able to pass under it. When we arrived and mentioned the matter to the Prophet he said, ''Eat a provision which God has brought forth for you, and give us some to eat if you have any." He said they sent some of it to God’s messenger and he ate it.
