Imam Muhammad al-Baqir (may Allah be pleased with him) narrates from Imam Zayn al-Abidin (may Allah have mercy on him), who reports from Sayyiduna Jabir (may Allah be pleased with him): The Noble Prophet (peace and blessings be upon him) used to recite the takbir after the Fajr prayer on the day of ‘Arafah and continued to recite it until the ‘Asr prayer on the last day of the days of Tashreeq. He would recite this takbir after completing the obligatory prayer and saying salam.
