98. Why did God create things which are dangerous to mankind?

The Holy Qur’an states:

الَّذِي أَحْسَنَ کُلَّ شَيْ‌ءٍ خَلَقَهُ

“He Who has made everything which He has created most good.”1

So even the poison of a snake in the snake’s body has benefits, although in the bodies of mankind it is fatal. As much as the saliva in our mouths is beneficial to us, if spat on another person, is an insult.
