1_The chapter on what one says if one sees the crescent and what one says if one sees the moon

474_ We have related in the Musnad of Al-Dāramī and the book of Al-Tirmidhī, on the authority of Ṭalḥa Ibn ʿUbayd Allah, may Allah be pleased with him, that when the Prophet, may Allah’s prayers and peace be upon him, saw the crescent he would say: “O Allah, bring the crescent upon us in safety and faith, and in peace and Islam. My Lord and your Lord is Allah.” Al-Tirmidhī said, ‘It is a ḥasan ḥadīth.’
