“I asked (Imam) abu ‘Abdallah (a.s.) about a man who was opposed by two people of his own faith in an issue that they both narrated. One of them said it to be obligatory and the other said it was prohibited. How it can be solved?” The Imam replied, “He must wait until he finds one who would inform him and until then he is not under any pressure.” In another Hadith it says, “Whichever answer he follows in obedience for his ease.”
