Hadith 3447
Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: The people tried to sight the new moon of the first (of the month), and I saw it. I informed the Prophet Muhammad (peace and blessings be upon him) about it, so the Prophet (peace and blessings be upon him) fasted and ordered the people to fast as well.
