Al-Saffar, from Ibrahim ibn Hashim, from Zakariyya ibn Yahya al-Kindi al-Raqqi, from Dawud al-Raqqi, from Abu Abdillah عليه السلام, peace be upon him: Imam عليه السلام said: “Look for the old crescent in the east in the morning. If it is not seen, then the crescent here is a new crescent, regardless of whether people later see it or do not see it.”
