 4. Muhammad ibn Ahmad has narrated from Muhammad ibn Khalid from al-Nadr ibn Suwayd from Yahya al-Halabi from ‘Imran ibn A‘yan from Ju‘ayd al-Hamadani who has said the following. “Once I asked Ali ibn al-Husayn , “By what mean do you issue judgments?” The Imam  said, “We judge by the laws of Allah and the judgment of the family of David. If a case would frustrate us the Holy Spirit inspires us with its laws.”
