Halal crypto glossary

Mudarabahمضاربة

A profit-sharing partnership where one party provides capital and the other provides labour or expertise. Profits are shared by ratio; losses are borne by the capital provider unless caused by misconduct. The closest classical analogue to a managed-investment subscription.

Definition

Mudarabah (مضاربة) is the classical Islamic partnership contract in which one party — the rabb al-mal — provides capital, and the other — the mudarib — provides labour, expertise, and management. Profits are shared by a pre-agreed ratio. Losses, by classical rule, are borne by the rabb al-mal unless they result from the mudarib's negligence or misconduct.

The mudarabah structure is one of the foundational profit-and-loss-sharing (PLS) contracts in Islamic finance. It is the analytical backbone of modern Islamic banks' "investment account" deposits and is widely used in sukuk structures.

Why mudarabah matters for crypto trading

A naïve framing of HalalCrypto as a mudarabah is tempting: customer provides capital, HalalCrypto provides the trading expertise, profits should be shared. But that framing is wrong, and the correct framing matters for Shariah analysis.

What HalalCrypto actually is:

  • Subscription service for software (the bot) and screening methodology (the AAOIFI-aligned framework).
  • The customer retains custody of their capital throughout — funds never leave their exchange account.
  • The customer retains all gains and bears all losses from trades. We do not share in profit and do not absorb loss.
  • The customer pays a fixed monthly subscription ($49 / $69 / $99) regardless of trading outcome.

This structure is closer to ijarah (a service for which a fee is paid) plus wakalah (an agency arrangement for the bot to execute trades within strict pre-defined parameters) than to mudarabah. Critically, this is not a mudarabah and we do not market it as one.

Why this distinction matters

A real mudarabah would create different obligations and exposures. The capital provider would have legal claim on a share of profits the manager held; the manager would have fiduciary obligations beyond software service. By being clear that HalalCrypto is a subscription tool rather than a fund manager, we keep the customer firmly in control of their capital and avoid creating implicit fiduciary structures we are not licensed to operate as.

Customers seeking actual mudarabah-structured Shariah investment vehicles should look at regulated Islamic asset managers (e.g., Wahed Invest, Saturna Capital's Amana funds, regulated GCC sukuk funds) — those are licensed for the mudarabah role. HalalCrypto serves a different need: deterministic, auditable execution discipline applied to a customer's own self-directed crypto allocation.

Launch-copy implication

Because HalalCrypto is not structured as mudarabah, the website must avoid language that suggests pooled capital, shared profits, guaranteed performance, or manager custody. The correct launch copy is subscription-service language: the customer pays a fixed fee for access to software, screening, alerts, and constrained execution. That wording is not cosmetic. It reduces regulatory ambiguity, protects users from misunderstanding the risk allocation, and keeps the Shariah analysis anchored in the contract that actually exists.
