83. A number of our people has narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa‘id from al-Nadr ibn Suwayd from al-Qasim ibn Sulayman from Sama‘a from abu ‘Abdallah (a.s.) about the words of Allah, the Most Majestic, the Most gracious. “. . God will grant you a double share of mercy, ( al-Hassan and al-Husayn ) a light by which you can walk. .” (57:28) The Imam (a.s.) said
“Light means the Imam that you would follow.”
