The Future Scientist Series : Letter 16

 The Earth We Will Leave Behind : A Father's Last Letter on Environmental Applications—and His First Letter About Life

My beloved Ayan/Saad,

Assalamu Alaikum wa Rahmatullahi wa Barakatuh.

Today, I write this letter with a heart that is both happy and a little emotional.

Happy...because we have reached the end of a beautiful journey.

Emotional...because endings always remind us how quickly time passes.

It feels like only yesterday that I wrote the first letter.

I asked you a simple question: "Why you should study Environmental Applications?"

Since then, we have travelled farther than I ever imagined. Together, we walked through forests where every tree had a story. We watched rivers carrying memories from mountains to oceans. We discovered that soil beneath our feet is alive. We learned that air, though invisible, is among Allah's greatest blessings.

We stood beside farmers who feed the world. We looked through satellites orbiting hundreds of kilometres above the Earth. We imagined future cities powered by sunlight and guided by intelligence.

But today...I do not want to speak about forests.          Or rivers.       Or pollution.

Today, I want to speak about you.

 

One Day...

One day, these letters will become old. The paper may become yellow. The technology we discussed may become outdated. Artificial Intelligence will become more intelligent. New discoveries will replace today's discoveries.

Some of today's environmental problems may be solved. New ones will appear.

But I hope one thing never changes.

I hope the young boy reading these letters never loses his curiosity.

Because curiosity is one of Allah's greatest gifts.

It is curiosity that asks,

§  "Why is the sky blue?"

§  "Why do birds migrate?"

§  "How does a seed know which way to grow?"

§  "Can we build cities that produce no waste?"

The day curiosity dies... learning ends.

Never allow that day to come.

 

What Environmental Science Really Taught You

Perhaps you think these sixteen letters were about:

ü  ecosystems,

ü  soil,

ü  air,

ü  water,

ü  technology,

ü  or climate change.

Not really.

Those were only the classrooms. The real lessons were different.

v Environmental science taught you that everything is connected. Faith taught you that everything is entrusted.

v Science taught you to observe carefully. The Qur'an taught you to reflect deeply.

v Engineering taught you to solve problems. The Sunnah taught you to serve others with mercy.

When these come together, they shape not merely a student, but a human being.

 

The Three Questions

As you grow older, people will ask you many questions.

Ø  "What career have you chosen?"

Ø  "Where do you live?"

Ø  "How much do you earn?"

Those questions matter.

But I hope you also ask yourself three questions every year of your life.

First

What have I learned this year that made me a better person?

Not merely smarter. Better.

Second

Whose life became easier because I was here?

Perhaps your family. Perhaps your neighbours. Perhaps strangers you never meet.

The Prophet taught us that the best people are those who benefit others. Make that your measure of success.

Third

If Allah were to ask me today about the trust He placed in my hands, what would I say?

§  Not only the trust of wealth.

§  Or time.

§  Or talent.

§  Also the trust of the Earth.

§  The rivers.

§  The animals.

§  The trees.

§  The people who depend on them.

Success          :           The world has many definitions of success.

Some count money.                        Others count followers.                 Others count awards.

I want to share your Abba's definition.  

A successful person is someone who:

v Leaves more kindness than he found.

v Leaves more knowledge than he received.

v Leaves more hope than he inherited.

v Leaves the Earth healthier than when he arrived.

That is success.

Remember the Earth Is Not Ours

When people buy a house, they often say,         "This is my land."

When countries draw borders, they say,                        "This is our territory."

But the Qur'an reminds us of a greater truth.    Everything belongs to Allah.

We are only travellers that have come to this examination hall called Earth for a test. Temporary caretakers.  Think of a traveller spending one night in a guest house or examination center.

Would he tear down the walls?    Pollute the garden?             Waste the food?

Of course not. Because he knows it is not his.

The Earth is Allah's guest house.

We have been invited for a short stay for examination purpose.

May we leave it in better condition than we found it.

 

Your Children

Perhaps one day, many years from now, Allah may bless you with children.

Maybe one evening your son or daughter will ask: "Abbu... did you know about climate change?"

You will answer,                                                                  "Yes."

"Did people know forests were disappearing?"            "Yes."

"Did people know rivers were polluted?"                       "Yes."

Then they may ask the question that matters.               "What did you do?"

I hope your answer will not begin with,                         "Someone should have..."

I hope it begins with,                                                          "I tried..."

Because Allah never asks us to control the outcome. He asks us to be sincere in our effort in the test.


Faith Meets Science

Allah says: "It is He who has made you successors (khala'if) upon the earth..."  Surah Fatir 35:39)

Notice that Allah calls us successors.

Each generation inherits the Earth from the previous one.    Not as owners.           As trustees.

One day... your generation will hand this trust to another.

The question is not whether the Earth will survive. Allah's creation has endured for ages.

The real question is: What condition will we leave it in?

 

The Prophet Muhammad said: "When a human being dies, all his deeds come to an end except three: ongoing charity, beneficial knowledge, and a righteous child who prays for him." (Sahih Muslim)

As I wrote these letters, I often thought about this hadith. Perhaps these letters become a small piece of beneficial knowledge.

Perhaps they inspire you to plant one tree. Protect one river. Teach one child. Invent one useful technology. Help one farmer. Conserve one wetland.

Or simply become a man who treats Allah's creation with mercy.

If they do... then these letters will continue working long after both of us have finished reading them.


 

Your Final Examination

No school will conduct this examination. No invigilator will supervise it. No marks will be awarded.

The questions are simple.

When you waste water...                                       what do you choose?

When you see injustice towards nature...                       what do you do?

When technology offers profit but harms people...what decision do you make?

When no one is watching...                                               who are you?

Those answers will define your life far more than any board examination.

 

There Is One Last Assignment

I promised you missions throughout these letters. This one is different. There is no deadline. No marks. No submission.

I simply ask you to write a letter.

Not today.     Not tomorrow.         One day, when you are ready.

Write a letter to your own child.

Tell them:

ü  what you learned,

ü  what mistakes humanity made,

ü  what beauty still remains,

ü  and why protecting Allah's creation is worth dedicating a lifetime to.

When that day comes...      this series of letter will truly be complete.

 

Before I Fold This Final Letter...  Ayan/Saad!!!

One day you will realise that fathers quietly grow older while their children quietly grow up.

There may come a time when these letters are all that remain of our conversations about Environmental Applications.

If that day ever comes, I hope you will remember not the words... but the intention behind them.

v I never wanted you to become the smartest student in your class. I wanted you to become the kind of man whose knowledge brings mercy to the world.

v If, years from now, you plant a tree because of these letters... they have succeeded.

v If you conserve water because of these letters... they have succeeded.

v If you design a cleaner technology because of these letters... they have succeeded.

v If you raise your own children to love Allah by caring for His creation... they have succeeded beyond anything I could ever imagine.

 

A Father's Final Prayer

My beloved son, I pray that Allah grants you a heart that never becomes hard.

v A mind that never stops asking questions.

v Hands that always build rather than destroy.

v Eyes that continue to see wonder in His creation.

v Knowledge that benefits humanity.

v Wealth that never corrupts your character.

v Humility that grows with your success.

v Friends who remind you of Allah.

v Courage to stand for what is right.

v Compassion for every living creature.

v And when your own journey on this Earth is complete, may you return to your Lord having fulfilled the trust He placed in your hands—with gratitude, integrity, and hope.

 

The Last Words

The purpose of education is not simply to make a living.

It is to make a life that is worth living.

The purpose of science is not simply to understand the world.

It is to protect and improve it.

The purpose of faith is not simply to prepare for the Hereafter.

It is to guide how we live in this world so that both this life and the next are enriched.

And the purpose of these letters... was never really to teach you Environmental Applications.

It was to remind you that every leaf, every river, every bird, every mountain, every breath, and every human being is part of a magnificent trust from Allah.

Take care of that trust.

And one day, when you stand before your Creator, may He say of you:

"He honoured the trust I gave him."

That is the success your Abba prays for.

With all my love in this world, with endless prayers for your Hereafter, and with gratitude to Allah for the privilege of being your father,

Always and forever,

Your Abbu 🌿
