There is an answer to this question, and it is kinder than most of us expect.
Islam does not treat rest as wasted time. A child lying on the carpet making a noise like a lorry is not wasting time. Nor is the half hour you spent drinking tea that went cold while you stared at the garden. What the sources keep circling back to is something much narrower than busyness or idleness, and it is worth getting right, because the wrong answer leaves a parent anxious about ordinary family life for no good reason.
The word that comes closest is ghaflah, heedlessness, the state of being switched off to whatever is actually in front of you. Not stillness. Not slowness. Absence.
What the sources keep pointing at
Surah al-‘Asr, the short chapter near the end of the Qur’an whose name carries the sense of the late afternoon or the passing age, opens with an oath by time itself. It then names who comes out of time with something in their hands: those who believe, who do good, and who hold one another to truth and to patience (103:1-3). Nothing in that list is about efficiency, or about filling every hour.
There is also a well-known narration recorded in al-Bukhari, the most rigorously checked of the hadith collections, compiled by Muhammad ibn Isma’il al-Bukhari (may Allah have mercy on him). In it the Prophet Muhammad ﷺ said that there are two blessings many people are heedless of: their health, and al-faragh, free time, the unclaimed hours that nobody else has a claim on.
Read that one slowly, because it is doing something you might not expect. Free time is called a blessing. It is not the fault. The fault is sleeping through it.
Scholars over the centuries have described time as an amanah, a trust, meaning something handed to you to look after and hand back. A trust does not have to be guarded nervously every second. It has to be treated as though it belongs to someone. That is a very different feeling in the chest, and it is the feeling I would want any parent to walk away with here.
Two questions that sort out most of it
When I am honestly unsure whether an hour went to waste, I find that two questions do almost all the work.
Did I choose this, or did it choose me?
An hour in the park with a four year old who wants to count every pigeon is chosen. An hour of scrolling that began because you were waiting for the kettle is not chosen, it simply happened to you. The tradition does not look down on permissible enjoyment or on play, and children in particular are meant to play. What it keeps warning about is lahw, idle amusement, in the specific sense of something that carries you off without your consent and leaves you unable to say where you went.
Is anything left over afterwards?
Some time leaves a residue. You remember it. Somebody was fed, or taught, or comforted, or you came away a little closer to Allah than you were. Other time evaporates completely, and by Thursday you could not say what Monday evening contained.
Neither question is about how much you got done. Both are about whether you were there.
A child of four to seven cannot do this on their own
Here is the part that matters for a parent, and it is the reason I think this question is worth more than a theological shrug.
Small children have no concept of a wasted hour. You cannot sit a five year old down and talk to her about the value of her time, and honestly you should not try. What a child that age does have is an almost supernatural ability to notice what the adults around her notices. She clocks what you point at. She clocks what you name out loud.
So the way a young child learns that time carries weight is not by being told. It is by hearing someone in the house say, out loud, what today had in it. That is the whole mechanism. It is almost embarrassingly simple, and it takes about two minutes.
The thing you could try tonight
Tonight, after the lights are off and before your child has properly settled, say one sentence out loud. Name one of the Names of Allah, in Arabic al-Asma al-Husna, the beautiful Names by which Allah describes Himself, and then give the day’s evidence for it.
It sounds like this. “Today Allah was Ar-Razzaq for us, the Provider. There was dinner on the table, and it has been a tight week.” Or: “Allah is As-Sami’, the All-Hearing. You whispered that du’a in the car and I did not even hear it. He did.”
If it rained and there were worms all over the path on the school run, that is Al-Khaliq, the Creator, and your child will have far more to say about the worms than you do. If somebody at the GP let you go ahead of them in the queue, that is Al-Latif, the Subtle and Kind, arranging something small that nobody organised.
Then, and this is the bit that does the real work, ask your child for theirs. “What was today?” Expect nonsense for the first few nights. Expect “Allah made my bike.” Take it. A four year old reaching for a Name of Allah to describe their own Tuesday is the thing you are after, and it does not need to be elegant.
That is one idea. Not a routine, not a chart on the fridge. One sentence, said in the dark.
Why naming it changes the next day
Barakah is the word for blessing in the sense of increase, more coming out of something than went into it. Parents often hope for barakah in their time and quietly assume it means somehow getting more hours. It tends to show up differently: the same hours, carrying more.
Two minutes at bedtime does not lengthen the day. What it does is go backwards through the day and pick things up. The worms get picked up. The whispered du’a gets picked up. The cold tea in the garden turns out to have had something in it after all, because somebody said so out loud before sleep.
Do that for a fortnight and you will notice your child starting to do it without being asked, usually at the least convenient moment, usually in the supermarket. That is the point at which the question of wasted time quietly answers itself in your house.
Where the screens come into it
I am not going to tell you that screens are what Islam means by wasting time, because that is not what the sources say and you have heard it enough.
What I will say is this. An hour of television in our house passes without anybody naming a single thing in it. That is the whole difference. Not the screen. The silence afterwards. If anything, the easiest fix is not removing the hour, it is adding the two minutes at the end of the night, so that something from the day gets said aloud rather than nothing at all.
Start there. It is a far smaller ask than a screen ban, and it works on days when you have nothing left.
If you would rather have it already laid out
Some evenings you will not be able to think of a Name, and that is not a failing, it is just half past seven. That is the gap the book I wrote is meant to sit in.
“Getting to Know Allah” is a printable activity book for ages four to seven, £9, available on Riwaya. It takes all 99 Names of Allah and sorts them into ten themes, and for every Name there is a plain-English meaning, a short story, a du’a and a page to colour in. You print the pages you want, at home, when you want them. Nothing to log into, nothing running in the background.
Most parents who use it tell me the surprise is how much of it they are learning themselves, which I think is the honest truth about teaching a child anything.
There is no catching up to be done here. Whatever today turned out to be, it still had Allah in it somewhere, and a four year old is perfectly capable of finding the place if you ask them to look.
