9. It was narrated to us by Muhammad b. Musa b. al-Mutawakil who said it was narrated to us by Abdillah b. Ja’far al-Himyari from Ahmad b. Muhammad b. Isa from al-Hassan b. Mahbub from al-Hussain b. Abi Hamzah who said: The narrator asked Imam Muhammad Baqir 
or Imam Ja’far Sadiq , “Can I postpone fasting for three days of a month till winter for I would find it easier to fast then?” Imam replied, “Yes, but do not reduce their number.”
