بِسْمِ اللهِ الرَّحْمٰنِ الرَّحِيْم
Bismillāhi r-raḥmāni r-raḥīm
"In the name of Allah, the Most Gracious, the Most Merciful"
Bismillah opens the Quran and accompanies almost every action in Islamic life. On a memorial it marks the stone as belonging to Allah's mercy and care. It is the most commonly chosen front panel phrase.
