Abu Wa'il narrates: Sayyiduna Ali (may Allah be pleased with him) and Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) did not recite "Bismillahir-Rahmanir-Rahim" aloud, nor did they say "A'udhu billah" or "Amin" aloud.
Al-Tabarani recorded it in al-Mu'jam al-Kabir. Its chain contains a narrator Abu Sa'd al-Baqqal; he is "thiqah" (trustworthy) and a mudallis (one who conceals defects in the chain).
