Allahumma-ftah li abwaba rahmatik.
O Allah, open the doors of Your mercy for me.
Allahumma inni as’aluka min fadlik.
O Allah, I ask You for Your bounty.
Entering with a request for mercy
Sahih Muslim 713a gives the entry wording. Its request helps a reader understand arriving for worship as a moment of dependence on Allah.
Learn the words before your visit if possible. A short accurately understood text is more useful than rushing through a phone screen while blocking the doorway or missing the congregation.
Leaving with a request for bounty
The same report gives different wording for leaving. The source cards preserve this distinction instead of combining entry and exit into one quotation.
Leaving to resume work, family or other responsibilities can be a moment to reflect on good beyond the mosque. That reflection is an ordinary application of meaning, not an extra ritual required by the report.
The wider etiquette lesson
Foot order, a greeting prayer, salawat and questions about particular mosque arrangements need their own references and teaching. These two cards are not a complete etiquette manual.
Respect other worshippers, local arrangements and those who may be continuing prayer. A saved page should support learning without becoming a distraction in a shared worship space.
Common questions
Are entry and exit the same words? No; mercy and bounty are distinct requests in the report. Is a repetition count given? This page adds none. Does the collection replace a prayer lesson? No. Where can I find more detail? The individual entering-mosque and leaving-mosque pages explain the same sources with a narrower focus.
