Think of the biggest, most beautiful tree you have ever seen. Branches reaching high into the sky. Sweet fruit hanging down. Birds singing inside it. Now here is a secret: the most important part of that tree is the part you cannot see.
Under the ground, in the dark, are the roots. They hold the tree up, and they drink the water. The taller the tree grows, the deeper its roots go. That is why the wind can huff and puff all it likes, and the tree just stands there, calm and strong.
In the Qur'an, Allah draws us this very picture. He tells us that a good word is like a good tree, with a root planted firm in the ground and branches reaching high into the sky, giving its fruit again and again by its Lord's permission. This kind of picture is called a parable, a word-painting Allah gives us so our hearts can understand.
So what is a good word? The best word of all is saying there is no god but Allah. And a good word is also a kind word, a true word, a gentle word. Like saying thank you. Like saying sorry. Like telling someone about Allah in a soft voice. A good word is sweet like cool, clean water, easy to take in, never hard and shouty. Even the right words stop being good if we throw them like stones.
And here is the wonderful part: when you say a good word, it is like planting a seed. Maybe you cannot see anything happen right away. That is okay! Seeds always do their first growing underground, secretly, where nobody can watch. Allah takes care of that hidden part Himself.
Think about what a big, good tree does all day long. It gives shade to anyone who is hot. It gives fruit to anyone who is hungry, even strangers passing by. It lets birds build their nests, and bees come to visit. Everybody loves being near it. A person full of good words is just like that tree: people feel happy and safe around them.
But a tree with tiny, shallow roots? One big storm, and over it goes. So we grow our roots too, quietly, on the inside: loving Allah, learning about Him, and talking to Him even when nobody is watching. That is how a heart grows strong enough for any windy day.
And the fruit? Allah says the tree gives its fruit by His permission. That means when you plant kind words, Allah decides how they grow. He can grow them bigger and more beautiful than we can imagine, even much later, in places we never get to see.
So tonight, plant one little seed before you sleep. Say a good word: Alhamdulillah, which means all praise is for Allah. And while you dream, somewhere in the quiet dark, Allah will be growing something beautiful from it.
