Humayd ibn Ziyad has narrated from al-Hassan ibn Muhammad from more than one person from Aban ibn ‘Uthman from ‘Abd al- Rahman ibn abu ‘Abd Allah who has said the following: “This is concerning my question before abu ‘Abd Allah (a.s.), about selling gold in exchange for dirham. He (the Imam) said, ‘Send a messenger to receive the price saying, ‘Give that and take this.’”
