And it was narrated by Muhammad ibn Abi Umayr, from Al-Ala' ibn Sayabah, from Abu Abdullah عليه السلام, who said that Abu Ja'far Imam Muhammad ibn Ali Al-Baqir عليه السلام, said: "The testimony of one who hastens ahead of the pilgrims is not accepted, as he has killed his mount, consumed his provisions, exhausted himself, and neglected his prayers." It was asked: "What about the muleteer, the camel driver, and the sailor?" Imam عليه السلام said: "There is no harm in them; their testimony is accepted if they are righteous."
