2-45 Muhammad ibn al-Hassan ibn Ahmad ibn al-Walid - may God be pleased with him - narrated that Muhammad ibn al-Hassan al-Saffar quoted on the authority of Ahmad ibn Aba Abdullah, on the authority of Abdul Rahman ibn Himad, on the authority of Muhammad ibn Sin’an who linked it up through a chain of narrators to Abi Ja’far al-Baqir (MGB) that the Imam (MGB) considered two forms of shopping to be bad: just picking the goods without checking them, and buying goods without having ever seen them.
IsnādMuhammad ibn al-Hasan ibn Ahmad ibn al-Walid a rapporté: Nous a informé Muhammad ibn al-Hasan al-Saffar, d'Ahmad ibn Abi Abdullah, d'Abd al-Rahman ibn Hammad, de Muhammad ibn Sinan, transmettant d'Abu Ja'far (que la paix soit sur lui)
qu'il détestait la vente par le geste de la main sans voir la marchandise et l'échange de biens avant de les avoir vus.
