Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: When the Prophet (peace and blessings be upon him) saw the new crescent moon, he would recite:
'Allahumma ahillahu 'alayna bil-amni wal-iman, was-salamati wal-islam, wat-tawfiqi lima tuhibbu wa tarda, rabbuna wa rabbukallah'
(O Allah, make it rise upon us with security and faith, with safety and Islam, and with success in what You love and are pleased with. (O moon,) our Lord and your Lord is Allah Almighty.)
Al-Tabarani recorded it; its chain contains a narrator, Uthman bin Ibrahim al-Hatibi, in whom there is weakness, and the remaining narrators of this report are thiqat (trustworthy).
