Hadith 4:861
Abu Bakr narrated to us, he said: Muhammad ibn Bishr narrated to us, he said: Abd al-Aziz ibn Umar narrated to us, he said: Someone whom I do not accuse [of lying] narrated to me, from Ubadah ibn al-Samit, who said: When the Messenger of Allah (peace and blessings of Allah be upon him) saw the crescent moon, he would say: "Allah is the Greatest, Allah is the Greatest. Praise be to Allah, praise be to Allah. There is no power and no strength except by Allah. O Allah, I ask You for the good of this month, and I seek refuge in You from the evil of destiny and from the evil of the Day of Gathering."
حدثنا أبو بكر قال حدثنا محمد بن بشر قال حدثنا عبد العزيز بن عمر قال حدثني من لا أتهم عن عبادة بن الصامت قال كان رسول الله صلى الله عليه وسلم إذا رأى الهلال قال الله أكبر الله أكبر الحمد لله الحمد لله ولا حول ولا قوة إلا بالله اللهم إني أسألك خير هذا الشهر وأعوذ بك من شر القدر ومن شر يوم الحشر
