Sayyiduna Ibn Umar (may Allah be pleased with them both) said: When the Messenger of Allah (peace and blessings be upon him) saw the new moon of the first night, he would say:“ «اَللّٰهُ أَكْبَرُ اَللّٰهُمَّ أَهِلَّهُ عَلَيْنَا ....... الخ» That is, O Allah, let this moon rise upon us with security, faith, safety, Islam, and guidance. O moon, our Lord and your Lord is Allah, the Exalted.”
