Dua when sighting the new crescent moon

that when the Prophet ﷺ would see a crescent moon, he would say:

allāhumma ahlilhu ʿalaynā bi-al-yumni wa-al-īmān, wa-al-salāmati wa-al-islām, rabbī wa-rabbuka Allāh

(O Allah, bring it over us with blessing and faith, and security and Islam. My Lord and your Lord is Allah.)”  

أَنَّ النَّبِيَّ ﷺ كَانَ إِذَا رَأَى الْهِلاَلَ قَالَ:

«(اللَّهُمَّ أَهْلِلْهُ عَلَيْنَا بِالْيُمْنِ وَالإِيمَانِ وَالسَّلاَمَةِ وَالإِسْلاَمِ رَبِّي وَرَبُّكَ اللَّهُ)»
