Living day to day with money you will be asked about
Most guidance on Islamic finance is written for scholars or for bankers. This is written for someone deciding, on an ordinary Tuesday, whether to make a purchase, what to do with the interest their bank just paid them, and whether they are giving enough.
وَٱلَّذِينَ إِذَآ أَنفَقُوا۟ لَمْ يُسْرِفُوا۟ وَلَمْ يَقْتُرُوا۟ وَكَانَ بَيْنَ ذَٰلِكَ قَوَامًا
“And those who, when they spend, are neither extravagant nor niggardly, but hold a medium between those.”
“আর তারা যখন ব্যয় করে, তখন অপব্যয় করে না এবং কৃপণতাও করে না; বরং তারা এ দুয়ের মাঝামাঝি মধ্যপন্থা অবলম্বন করে।”
The standard is not poverty and it is not abundance. It is a considered middle — which means someone has to be doing the considering, transaction by transaction.
Five habits, in the order they happen
None of these are difficult. What makes them work is that they are daily, and that each one is small enough to survive a bad week.
- 01
Begin with intention
Before the earning and the spending there is the niyyah. Money sought to provide for a family, to stay free of debt, or to be able to give, is money sought for a reason — and a reason makes the hard choices easier later in the day.
- 02
Record what moves
Every amount in and out, on the day it happens. Not because bookkeeping is pious in itself, but because you cannot weigh what you cannot see, and memory quietly rewrites the month in your favour.
- 03
Sort want from need
The same purchase can be either, depending on the week. Naming which one it was — at the moment of spending, not at the end of the month — is what turns a list of transactions into a habit you can actually change.
- 04
Give something
Sadaqah does not have to be large or annual. A small amount given regularly and quietly keeps giving as part of the rhythm rather than an event you brace for once a year.
- 05
Reckon before you are reckoned
A short review — weekly is plenty. What came in, where it went, what was doubtful, what to put right. It is a small accounting, taken willingly, against a larger one that is not optional.
“Reckon before you are reckoned” is attributed to ʿUmar ibn al-Khaṭṭāb (may Allah be pleased with him), and is widely transmitted as a saying rather than a hadith of the Prophet ﷺ.
Eight moments that come up every month
The principle on one side, what it actually asks of you on the other.
When
Your salary arrives
Wealth is a trust you are answerable for, not simply yours to consume.
What to do
Record the income the day it lands, and decide the giving before the spending — not from what happens to be left.
When
The bank credits interest
Riba is not a gain you may benefit from.
What to do
Keep it separate from your own wealth and dispose of it in charity without expecting reward for it. This is the position most scholars take; ask yours if your situation is unusual.
When
You are about to buy something
Neither extravagant nor withholding — the middle way.
What to do
Name it as a want or a need before you pay, not afterwards. Extravagance is rarely one large purchase; it is many small ones nobody weighed.
When
You need to borrow
Debt is a serious obligation, and interest-bearing debt compounds the problem.
What to do
Write down the amount and the term. Prefer an interest-free loan (qard hasan) or a fixed-price deferred sale over interest-bearing credit, and repay early where you can.
When
Someone owes you
Record it, and be gentle with a debtor in difficulty.
What to do
Write it down at the time, with the term agreed. Granting more time to someone genuinely unable to pay is encouraged, not weakness.
When
You are trading or selling
Honesty in dealing, and no concealment of defects.
What to do
Disclose what is wrong with the thing you are selling, keep the terms clear, and keep a record both sides could check.
When
The income is doubtful
Income you cannot establish as lawful should not be mixed in with income you can.
What to do
Separate it rather than mixing it into your wealth, and seek a ruling from someone qualified before you rely on it.
When
A lunar year passes above Nisab
Zakat is an obligation on wealth, not a donation from it.
What to do
Total your zakatable assets, subtract immediate liabilities, and pay 2.5% — checked against the working, not estimated.
Riba is rarely something you sign up for
Very few people set out to deal in interest. It arrives attached to ordinary products, in amounts small enough to ignore, which is exactly why it needs looking for.
Where it commonly turns up
- Conventional savings and current accounts that credit interest
- Credit card balances carried past the interest-free period
- Conventional mortgages, car finance and personal loans
- Fixed deposits, bonds and interest-bearing certificates
- Late-payment penalties calculated as a percentage over time
- Buy-now-pay-later plans that add a financing charge
Interest already received is generally not treated as yours to enjoy: the common position is to give it away without seeking reward for the giving, keeping it out of your own wealth and out of your Zakat base. Where you stand on a specific product — a mortgage in a country with no Islamic alternative, say — is a question for a qualified scholar, not for an app.
وَأَحَلَّ ٱللَّهُ ٱلْبَيْعَ وَحَرَّمَ ٱلرِّبَوٰا۟
“Allah has permitted trade and has forbidden interest.”
“আল্লাহ ব্যবসাকে হালাল করেছেন এবং সুদকে হারাম করেছেন।”
One is owed, the other is offered
They are often spoken of together and they are not the same thing. Confusing them is how people end up believing they have discharged an obligation with a donation.
Obligatory
Zakāh
Due on qualifying wealth that has stayed above the Nisab threshold for a full lunar year. The common rate on monetary wealth is 2.5%. It is calculated, not estimated, and it is a right the recipients hold over your wealth rather than a kindness from you.
- · Assessed on assets, less immediate liabilities
- · Nisab is the lower of 87.48g gold or 612.36g silver
- · The year (Hawl) restarts if you fall below Nisab
Voluntary
Ṣadaqah
Given freely, in any amount, at any time, and not restricted to money. It does not reduce what you owe in Zakat, and it is at its most useful as a habit — small, regular and unannounced — rather than as an annual gesture.
- · No threshold and no fixed rate
- · Can be time, help or goods, not only cash
- · Best kept quiet and consistent
Deenomics tracks both separately — see how the Zakat engine works.
This is general education, not a fatwa
Everything on this page describes mainstream, widely held positions in simple terms. Schools of jurisprudence differ on real details — what counts as zakatable, how certain contracts are treated, what to do where no Islamic alternative exists — and your circumstances may turn on exactly those details. Deenomics does not issue rulings. For a decision that binds you, ask a qualified scholar.
The guide travels with the numbers
All of this sits inside the app, next to the transaction you are looking at — so the ruling and the figure are never in two different places.
