15. Ali ibn Ibrahim has narrated from Muhammad ibn ‘Isa from Yunus from certain persons of his people who has narrated the following: “I once asked abu ‘Abd Allah عليه السلام, about testimony when it is presented before a judge; if he can issue a judgment on the basis of the testimony, which he does not know, without asking? He (the Imam) said, ‘In five things it is obligatory on people to accept them for the face value of the rule: guardianship, marriage, inheritance slaughtered animals and testimonies. If they apparently are safe and clear, it then is permissible to accept the testimony, and there is no need to ask about its indepth details?”
