Hadith 888
Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: When the Prophet Muhammad (peace and blessings be upon him) would see the new moon, he would supplicate: "O Allah! Let this moon rise upon us with security, faith, safety, and Islam, and with that which You love and are pleased with. (O moon!) Our Lord and your Lord is Allah, the Exalted."
