Sayyiduna Ali (may Allah be pleased with him) and Sayyiduna Ammar (may Allah be pleased with him) narrate: The Prophet (peace and blessings be upon him) used to recite "Bismillahir-Rahmanir-Rahim" aloud.
Al-Tabarani recorded it in al-Mu'jam al-Kabir. Its chain contains a narrator Jabir al-Ju'fi, whom Shu'bah, al-Thawri and Zuhayr bin Mu'awiyah declared "thiqah" (trustworthy); he is a mudallis (one who conceals defects in the chain), and people have declared him da'if (weak).
