لَا أَرْبَحَ اللَّهُ تِجَارَتَكَ
Transliteration
laa arba'ha Allahu tijaarataka
Translation
May Allah not profit your business.
Abu Hurairah narrates: The Prophet (ﷺ) said: "If you see someone buying or selling in the Masjid, say this:
لَا أَرْبَحَ اللَّهُ تِجَارَتَكَ
Transliteration
laa arba'ha Allahu tijaarataka
Translation
May Allah not profit your business.
Note
This is because the mosques were not built for this purpose.
Allah's house is for His remembrance and Salah only. This prayer keeps the space clean and stops worldly buying-selling from taking over worship areas.
Say Laa arba'ha Allahu tijaarataka. It means: may Allah not give profit to your business. Trading isn't allowed here.
The masjid is built for dhikr and salah only, not for earning money. Business in mosque breaks sunnah, so we say this prayer as a warning.
You can ask Allah for what you need. But real trade deals or selling items? Forbidden. If someone does it, this masjid prayer applies to them.
May Allah not profit your business. It's a strict statement to stop people from using Allah's house for worldly trade.
Entering mosque prayer is different. This specific prayer is only said when you see buying and selling happening inside.
Yes. Similar ban exists for announcing lost things. This trading prayer shows: the mosque isn't for public asset announcements.
Jami At-Tirmidhi 1321. It's a sahih narration teaching us correct adab and respect for Allah's house.
