# Islamic Layer

A first-class part of Atlas OS — woven into the OS and the device fleet, not bolted on.

## Components

| Layer | What it does |
|-------|-------------|
| Family-safe DNS | AdGuard Family + a hosts blocklist across the network |
| Content filtering | HaramBlur on browsers |
| Quran at logon | Recitation plays when the workstation logs in |
| Adhan + lock | At configured mosque salah times, the Adhan plays and the screen locks |
| Sunnah reminders | Recurring reminders surfaced across the device fleet |

## Salah timing

Prayer times are configured for your local mosque. At each salah time the fleet plays the Adhan and locks the active screen — a deliberate, enforced pause rather than a passive notification.

To configure your mosque: edit `atlas-os/islamic/config.json` with your mosque name and location (or GPS coordinates). The timing engine uses the MuslimSalat API.

## Where it lives

All assets and scripts live under the Atlas artifacts tree:

```
Sync/atlas-artifacts/atlas-os/islamic/
```

This keeps the layer versioned and reproducible alongside the rest of the Atlas OS configuration, and syncs across devices through the same Syncthing topology as the other artifacts.

## Principle

The Islamic layer is treated as core infrastructure: it ships with the OS, runs on the fleet by default, and is documented and version-controlled like every other service.
