Dua Upon sighting the crescent moon

اللَّهُ أَكْبَرُ، اللَّهُمَّ أَهِلَّهُ عَلَيْنَا بِالْأَمْنِ وَالْإِيمَانِ، وَالسَّلَامَةِ وَالْإِسْلَامِ، وَالتَّوْفِيقِ لِمَا تُحِبُّ رَبَّنَا وَتَرْضَى، رَبُّنَا وَرَبُّكَ اللَّهُ ⁽¹⁾.

Allahu akbar, allahumma ahillahu AAalayna bil-amni wal-eeman, wassalamati wal-islam, wattawfeeiqi lima tuhibbu watarda, rabbuna warabbukal-lah.
‘Allah is the greatest. O Allah, let the crescent loom above us in safety, faith, peace, and Islam, and in agreement with all that You love and pleases You. Our Lord and your Lord is Allah.
