By this isnad from Muhammad b. al-Husayn b. Abi’l Khattab from `Uthman b. `Isa from Abi Ayyub al-Khazzaz from Abi `Abdillah al-Sadiq (as). He said
Whoever swears by Allah must be truthful, and whoever is not truthful will have nothing with Allah. Whoever has someone swear by Allah must be pleased [with the outcome], and whoever is not pleased will have nothing with Allah.
