1. My father (rah) said: it was narrated to us by Sa’d b. Abdillah who said it was narrated to us by Ahmad b. Muhammad b. Isa from al-Hussain b. Sa’eed from Fadhalah b. Ayoob’ from al-Hassan b. Uthman from Ibn Muskan who said it was narrated to me by Ibrahim b. al-Muthana who said: The narrator asked Imam Ja’far Sadiq , “It is difficult for me to fast for three days every month. Is it enough that I give one dirham in charity for every fast?” Imam  replied, “Giving a dirham in charity is better than fasting for a day.”
