10. Through the same chain of narrators as that of the previous Hadith, the following is narrated: “Abu Ja‘far عليه السلام, has said, ‘The testimony of one who goes before al-Hujjaj (travelers for al-Hajj) as a precursor, is not acceptable because he kills his stumper, depletes his supplies, tires himself and treats his Salat (prayer) lightly.’ I then asked about the one who provides transportation for hire, camel man and boat operators. He (the Imam) said, ‘They are not bad and their testimony is acceptable if they are virtuous people.’”
