We were told by Sa’d bin Abdullah, that he said: We were told by Ahmad bin Muhammed bin Isa, with a connected chain (reaching) to al-Sadiq, Ja’far bin Muhammed, peace be upon them both, that he said: The least that achieves fulfillment from supplication after an obligatory prayer is that one says: «O Allah, send Your blessings upon Muhammed and the Family of Muhammed. O Allah, indeed, I ask You from every good which Your knowledge encompasses, and I seek refuge in You from every evil which Your knowledge encompasses. O Allah, indeed, I ask You for Your comfort in my matters, all of them, and I seek refuge in You from the disgrace of this world and the torment of the Hereafter.»
