 Mohammed bin Musa bin al-Mutawakkil, Allah may have mercy upon him, narrated to me from Abdullah bin Ja’far al-Himyari from … al-Asbagh bin Nubata related: We were gathering when Amir ul-Mu’minin  went out and asked about the reason of our gathering. “We are your Shia, Amir ul-Mu’minin,” we answered. He said, “But I cannot see the marks of the Shia on your faces.” “What are the marks of the Shia?” asked we. He  spoke: The Shia are pale-faced because of staying up at nights for offering prayers, bleary-eyed because of fear of Allah, and dry-lipped because of fasting. The dust of the submissive covers them.
