This Is My Faith - Al-fatlawi, Ali - الصفحة ٩٢ - Interpretation of Evils and Tribulations

Anwar: This is a very reasonable point; we should not rush into judgments, especially when we know that the Doer is Just and Wise.

Hasan: Now we’ll answer in details:

Looking at a phenomenon isolated from other ones is an incomplete look, because incidents are interconnected rings in an interlocked extended chain. So, we cannot judge a particular phenomenon or incident without noting what preceded it or what will follow it.

For example, when a storm hits a coast, it demolishes many houses and trees; this is an evil act for those it happens to them, yet it is a good thing for the ships sailing in the midst of the sea. It is also considered good and valuable when it is a way to pollinates flowers or when it moves the clouds bearing rain or when it dissipates the fumes and the smoke rising from factories that may affect the environment if they remain still, and many other benefits of winds.

We understand here that damage is partial, as it affects a particular individual or a small group, when it is compared to the public benefit it brings to many others.
