Sayyiduna Ubadah bin al-Samit (may Allah be pleased with him) narrates: When the Prophet (peace and blessings be upon him) saw the new crescent moon, he would recite:
'Allahu akbar, al-hamdu lillah, la hawla wa la quwwata illa billah. Allahumma inni as'aluka khayra hadhash-shahr, wa a'udhu bika min sharril-qadari wa min su'il-mahshar' (Allah is the Greatest; all praise belongs to Allah; nothing can happen except with the help of Allah Almighty. O Allah, I ask You for the good of this month, and I seek refuge in You from the evil of destiny and from an evil state at the Gathering (on the Day of Resurrection).)
Abdullah and al-Tabarani recorded it, and its chain contains a narrator who is not named.
